libg2c is the runtime library for g77, the fortran compiler for gcc 3.x.

Loooking at the R spec file, this is likely to be in gcc-g77 (or a 
dependency of that), and that is a dependency of the R-devel RPM.  Have 
you tried installing the latter: you will need it to install packages 

Googling got me to


which suggests that you need the libf2c RPM on RHEL4.
