[Rd] error from make: gcc -shared -L/usr/local/lib64 ... relocation R_X86_64_32...

[Prof Brian Ripley]

It is libg2c.a you are being told to recompile.

There ought to be a lib2gc.so* on your system.  On FC3

gannet% rpm -q --whatprovides /usr/lib/libg2c.so.0
libf2c-3.4.4-2.fc3
gannet% rpm -q --filesbypkg libf2c-3.4.4-2.fc3
libf2c                    /usr/lib/libg2c.so.0
libf2c                    /usr/lib/libg2c.so.0.0.0

which looks like the problem if it is missing.
