Hi all,

I'm trying to compile R 2.11.0 on a redhat machine, but I'm getting
the following error when I run ./configure:

checking whether gfortran appends underscores to external names... yes
checking whether gfortran appends extra underscores to external names... no
checking whether mixed C/Fortran code can be run... configure:
WARNING: cannot run mixed C/Fortran code
configure: error: Maybe check LDFLAGS for paths to Fortran libraries?

I don't really know what "LDFLAGS" is, but I've searched online and I
think this is something to do with not being able to find "libg2c.so".
It seems to be located here on my machine

So I'm wondering if this is what is wrong and how I can make the
configure script "see" the directory with this file, I'm a Linux
newbie by the way so go easy!
