Your problem is not the compiler.  It is the configure command that  
is wrong.  There is no problem building R with gfortran and gcc-4.   
The F77 define is probably necessary, but you should not need to add  
standard Fortran libraries.

The recommended configure command is
./configure --with-blas='-framework vecLib' --with-lapack --with-aqua
see http://cran.r-project.org/bin/macosx/RMacOSX-FAQ.html

BLAS and LAPACK are part of the Accelerate framework in MacOS X.   
Because you have omitted the '--with-blas' and '--with-lapack'  
options R is trying to build its own LAPACK which AFAIK is not  
supported on MacOS X.  Hence your problems.
