I want to install nghttp2 for my mac os but after I run command brew install nghttp2, I face this output:

I am running on an enterprise VM that i do not have normal access to, but can only use apps installed therein. I do not have access to the VM terminal either unfortunately.
I'm starting to try to work on a Linux computing cluster where some programs and libraries are made available through a system of environment modules.
I would like to install Haskell programs using stack (I should probably say that I'm not yet very familiar with stack).
stack is available as a module, so after doing module load stack, I tried stack setup, which failed, complaining about gmp missing:
$ stack setup
Preparing to install GHC (gmp4) to an isolated location.
This will not interfere with any system-level installation.
Downloaded ghc-gmp4-8.0.1.
Installed GHC.
The GHC located at
/pasteur/homes/bli/.stack/programs/x86_64-linux/ghc-gmp4-8.0.1/bin/ghc
failed to compile a sanity check. Please see:
http://docs.haskellstack.org/en/stable/install_and_upgrade/
for more information. Exception was:

The admin of the cluster told me that gmp was also available as an environment module, so I did module load gmp before trying again, and it seemed to work:

Then I tried to install hlint using stack:

It seems that when compiling ghc, stack was able to see gmp, but not when installing some packages.
I notice this warning: configure: WARNING: unrecognized options: --with-compiler. I don't know if this is relevant.
The environment module system seems to work by exporting some environment variables:
$ module show gmp
-------------------------------------------------------------------
/local/gensoft2/devmodules/gmp/6.0.0:
module-whatis Set environnement for gmp (6.0.0)
module-whatis topic_3316
prepend-path LIBRARY_PATH /local/gensoft2/lib/gmp/6.0.0/lib
prepend-path LD_RUN_PATH /local/gensoft2/lib/gmp/6.0.0/lib
prepend-path -d LDFLAGS -L/local/gensoft2/lib/gmp/6.0.0/lib
prepend-path CMAKE_LIBRARY_PATH /local/gensoft2/lib/gmp/6.0.0/lib
prepend-path C_INCLUDE_PATH /local/gensoft2/lib/gmp/6.0.0/include

prepend-path CMAKE_INCLUDE_PATH /local/gensoft2/lib/gmp/6.0.0/include
prepend-path -d CPPFLAGS -I/local/gensoft2/lib/gmp/6.0.0/include
setenv GMP_ROOT /local/gensoft2/lib/gmp/6.0.0
-------------------------------------------------------------------
The administrator told me that these environment variable are not always taken into account, and suggested to export LDFLAGS="-Wl,-rpath,$GMP_ROOT/lib $LDFLAGS" in my environment before trying, but this did not seem to have any effect on the issue.
I still obtain the following: error while loading shared libraries: libgmp.so.10: cannot open shared object file: No such file or directory
How can I get stack to reliably take into account development libraries that the environment modules system provides?
Edit
It seems that I can give the missing library paths on the command line to stack as follows:
$ stack --extra-lib-dirs=/local/gensoft2/lib/gmp/6.0.0/lib --extra-include-dirs=/local/gensoft2/lib/gmp/6.0.0/include install hlint

Is there a way to have this done automatically for every possible development library loaded by module?
I'm not sure this is completely reliable (environment modules for development libraries might not all export these variables), but passing -extra-include-dirs=${CMAKE_INCLUDE_PATH} and --extra-lib-dirs=${CMAKE_LIBRARY_PATH} to stack seems to work at least when installing hlint, scan and doctest.
I'm a bit confused about what would be the correct configuration file to use, and how, to make this automatic.
It seems that the corresponding settings in ~/.stack/config.yaml are taken into account (although the documentation mentions ~/.stack/global-project/stack.yaml).
The above-mentioned environment variables cannot be used as-is in the config file. I haven't determined what the exact reason. This could be either because their expansion results in something not syntactically correct (paths separated by ":" instead of ","), or because only plain text is permitted in the config file.
Therefore, the following works in the present case, but is not a general solution:
extra-include-dirs: [/local/gensoft2/lib/gmp/6.0.0/include]
extra-lib-dirs: [/local/gensoft2/lib/gmp/6.0.0/lib]

I'll tell ya I never post question anywhere because I can usually figure stuff out eventually. But I am not seeing anyone having this specific error anywhere. I see similar things about not having XCode... But I have that.

I ran into this problem because I thought I had everything set up but when I tried to make a new project I ran into this:

If you need 2.2.0 (the latest version), here's how I got it to work:
Install DevKit
Run the command below to install bluecloth:
gem install bluecloth
this will fail miserably when building "native extensions", but will successfully install the gem's source code.
Patch bluecloth.h file (for me, this is found in: D:\ruby\Ruby-1.9.3-p125\lib\ruby\gems\1.9.1\gems\bluecloth-2.2.0\ext), with the patch from here: https://gist.github.com/1539611
Go to bluecloth's gem installation folder. For me, this looks like below:
D:\ruby\Ruby-1.9.3-p125\lib\ruby\gems\1.9.1\gems\bluecloth-2.2.0
Run the following command:
rake gem
It may prompt you to install some other gems, follow accordingly.
When it's done, you should see a bluecloth-2.2.0.gem created. For me, it is found here:
D:\ruby\Ruby-1.9.3-p125\lib\ruby\gems\1.9.1\gems\bluecloth-2.2.0\pkg\bluecloth-2.2.0.gem
Go to bluecloth-2.2.0.gem location, and run the following command:
gem install bluecloth-2.2.0.gem --platform=ruby
It seems there is a bug/issue with version 2.0.10 of BlueCloth. You can try using an older version like 2.0.7:
gem install bluecloth -v 2.0.7
Which seems to work.
Also probably this worth checking latest version (2.2.0?) and if not work, report it back to gem author:
http://deveiate.org/projects/BlueCloth/query
This is the patched bluecloth.h code, for people in a hurry...

There's a fork on github that already includes the patch:
