ld problem under RH 5.0 with gpc rpm

I have installed (Redhat 5.0) gpc-2.0-1.i386.rpm, but running it on any pascal program produces an error: ld: cannot open crtbegin.o: No such file or directory (If I use gpc -S hello.pas, I _do_ get successful compilation; the problems clearly arise later.) Can anyone point me in the right direction on this? Specifically, are there configuration steps which must be taken _after_ rpm has completed its installation? Thanks, Doug Troeger
