glew comes with glewinfo, which reports availability of OpenGL features.

Installing glew on High Sierra and running glewinfo looks like this:

$ brew update

$ which glewinfo
/Users/nilsberg/brew/bin/glewinfo

$ glewinfo
dyld: Library not loaded: @rpath/libGLEW.2.1.dylib
  Referenced from: /Users/nilsberg/brew/bin/glewinfo
  Reason: image not found
fish: 'glewinfo' terminated by signal SIGABRT (Abort)

The problem seems to be that libGLEW is referenced via @rpath, but otool -l glewinfo confirms that there is not @rpath definition in the executable. I've put that into a gist together with the output of brew config and brew doctor

I was able to manually add the missing @rpath to the binary using install_name_tool:

sudo install_name_tool -add_rpath ~/brew/Cellar/glew/2.1.0/lib/ ~/brew/Cellar/glew/2.1.0/bin/glewinfo

With that change, glewinfo works.

I confirmed that manually building glew from the tarball in the Formula yields a glewinfo binary with correct @rpath.

brew install -s glew produces a binary without @rpath, though.

Unrelated to this particular issue, brew install --HEAD glew fails completely (gist with logs):

$ brew install --HEAD glew

Ping?

I'm new to using this issue template - do you wait for all the boxes in the template to be checked? Because I left those that do not apply to this issue unchecked, but I feel it is complete nonetheless.
