Hmm, gcc44 is unlikely to be a Fortran compiler.  You should not be 
patching the configure script, rather setting precious variables like 
F77 (see the R-admin manual).

The problem is in your Fortran setup. At a guess, it has a static 
libgfortran (unusual with gcc 4.x).  Take a look at 
src/library/modules/lapack/Makefile . You most likely have a line

Rlapack_la_LIBADD = # $(FLIBS) $(LIBR)

and need

Rlapack_la_LIBADD = $(FLIBS) # $(LIBR)

Either that, or your compiler and your dynamic libgfortran.so are 
mis-matched.
