This is not an issue with R, but with gfortran. See the following:

Also, I suspect you are using a precompiled gcc/gfortran, and it assumes
you have libmpc.so.2 <http://www.muliprecision.org> installed. If you
compile all of gcc, you won't see this problem. However, this is
probably not the simplest solution. I'd try the solution in the second
link above. Else, if `gcc --version` <= 4.4, get the compiled gfortran
at that version.
And as the output indicates it is 4.1.2. So this is an ancient Linux
(perhaps RHEL?), and you really need the gfortran (and libgfortran)
from the distribution.
Mixing an unreleased bleeding-edage gfortran with a gcc from early
2007 is not going to work well, most likely not at all.
P.S. `grep -R mpc.h R-2.11.1/*` indicates R does not depend on libmpc

Hello,
I have basic familiarity with Unix but by most standards a novice. I am
trying to install R on a linux machine and am following the instructions in
the R install and admin guide in terms of what is required to compile the R
source code. I downloaded R version 2.11.1 and extracted the files into my
home directory. I realize I need a FORTRAN compiler to help with this
process and have tried installing a few but still cannot past the
configuration step of installing R:
./configure --with-readline=no
Once I run this command after installing GFortran I get the following error:
...

When I check the version of Gfortran at the console command line I get this:
GNU Fortran (GCC) 4.6.0 20100407 (experimental) [trunk revision 158083]
Copyright (C) 2010 Free Software Foundation, Inc.
Even before this I tried the g95 fortran compiler and the same thing
happened, how can I fix this problem, any help on this matter would be
greatly appreciated.
Thanks
