[R] R linux install: FORTRAN compiling error

[Matt Shotwell]

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

http://gcc.gnu.org/wiki/GFortran#news (under heading "gfortran 4.5")

http://gcc.gnu.org/ml/fortran/2010-04/msg00061.html

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.

P.S. `grep -R mpc.h R-2.11.1/*` indicates R does not depend on libmpc
