Tim,

I certainly do not expect anything special, just normally "make
install" should not have issues, if "make" passes fine, right? What we
have with OpenMPI is this strange difference: if ./configure CC=icc,
"make" works, and "make install" - does not; if ./configure
CC=/full/path/to/icc, then both "make" and "make install" work.
Nothing needs to be searched, icc is already in PATH, since
compilevars are sourced in profile.d. Or am I missing something?

Thanks,
- D.
