> Hmm... To be honest I'm a novice at installing complex things, I'm a computer scientist by trade but I'm not very good at troubleshooting this kind of thing. Has anyone actually installed GROMACS on mac and what did you do? (Using the default gcc/g++ doesn't work for the AVX stuff)

I got it working, but with gcc, only.

I would try the following:
1.) Find  libiomp5.dylib
find / -iname libiomp5.dylib
2.) Update dyld search path by adding the directory from step 1
export DYLD_LIBRARY_PATH="${DYLD_LIBRARY_PATH}:/path/to/libiomp5"
to your .bashrc or GMXRC.bash

I downloaded the latest Intel C++ compilers and built Gromacs successfully (at least it appeared to be successful since I saw no error messages). I appended this line to my ~/.profile file: source /usr/local/gromacs/bin/GMXRC.bash, and restarted my terminal. Still, every time I type in a GROMACS command, such as "luck," it says "command not found." f I do echo $GMXDATA, it does return /usr/local/gromacs/share/gromacs, though.
