There has been discussion of this on R-devel in the context of the release
of 2.1.1.
FC4 contains gfortran, not g77 (unless you install everything when you
get g77 from gcc-3.2.3 in some compatibility RPM). This is not a bug: R
compiled on one OS (or even machine) is not expected to work on another.
-lg2c is part of gcc-3.x.y, and gfortran uses something like -lgfortran
(FC3's gcc4 didn't use the standard name, so I am being cautious).
I think it is fortuitous that R runs in your tests without crashing:
libRlapack.so is linked against libg2c.0.0 and actually calls entry points
in it. (The R executable is also linked but seems to contain no such
entry points.)
I would suggest installing 2.1.1 on Monday from the sources, or waiting
for a 2.1.1 RPM. I believe gcc-3.4.4 is still a better choice than
gcc-4.0.0 on ix86: it runs faster and there are several cases in which
4.0.0 appears to give incorrect answers. I am waiting for the eventual
release of 4.0.1 to test these more thoroughly. (See the notes in the
R-admin manual: fortunately FC4's gcc4 is just recent enough to avoid the
showstopper bug.)

Interesting spelling!
