Re: [AMBER] Fwd: some clues about yacc errors on OLCF rhea

Yes, I agree, I had considered following the long trail of config.h files
and Makefiles and trying to reset the YACC variable myself; but I imagined
I would maybe miss some as I don't know the entire workflow.

And yes, it is possible that other libraries that amber tries to build will
also have an issue with our openmpi, or at least our mpicc wrapper.

This is an especially difficult make for HPC systems exactly because of all
of the library building involved, as opposed to using variables that allow
the user to set the paths to the various libraries on the system.
