We got our system upgraded to from MPE 5.5 to 6.0 this morning.  I decided to reinstall the gnu environment so as to "be safe". However, I installed gnucore, gnugcc1, gnugcc2 and gnulibs.  When I try to compile anything I get the error:

gcc: installation problem, cannot exec `cpp': No such file or directory

 Uhhhh.. that can't be good and I have some socket code accessing T/I written and working flawlessly before that I am kind of counting on *sigh*  Anyone have any ideas where to start (yes, I tried reinstalling gnugcc again to no avail)?
