rcgtk's Issues

Could not find proper libLLVM

repro:

1. install gem using branch llvm-3.6

2. clean install llvm via brew

3. properly handle paths:

   export PATH=/usr/local/opt/llvm/bin:$PATH
   export CPLUS_INCLUDE_PATH=$(llvm-config --includedir):$CPLUS_INCLUDE_PATH
   export LD_LIBRARY_PATH=$(llvm-config --libdir):$LD_LIBRARY_PATH
   

4. make sure:

   echo $LD_LIBRARY_PATH => /usr/local/Cellar/llvm/3.6.2/lib:
   

5. call RCGTK::CG::LLVM, gets:

   LoadError: Could not open library 'LLVM-3.6': dlopen(LLVM-3.6, 5): image not found.
   Could not open library 'libLLVM-3.6.dylib': dlopen(libLLVM-3.6.dylib, 5): image not found
     from /Users/nami/.rvm/gems/ruby-2.3.1@asm-ruby/gems/ffi-1.9.14/lib/ffi/library.rb:147:in `block in ffi_lib'

6. Now I'm now sure where's the problem

BTW, seems it's finding libLLVM-3.6.dylib, but there's only libLLVM.dylib in /usr/local/Cellar/llvm/3.6.2/lib/
