Thanks for the answers. I replace lg2c with lgfortran. When I try to
compile now I get the following error message

ld: warning: in /usr/local/gcc-4.3.5/lib/libgfortran.dylib, file was
built for i386 which is not the architecture being linked (x86_64)
Actually I build the /usr/local/gcc-4.3.5/lib/libgfortran.dylib by
myself some days ago. But somehow the compilation produced a 32 bit
library but I do need a 64 bit library. So I would like to rebuild the
gfortran stuff. But where do I have to configure that libgfortran.dylib
is compiled for a 64 bit system?
I built the gfortran stuff this way:
In "/Users/toom/Downloads/gcc-4.3.5-base/obj-gcc-4.3.5" I typed the
following commands:
../gcc-4.3.5/configure --prefix=/usr/local/gcc-4.3.5/ --languages=fortran
make
sudo make install
and I got a gfortran in /usr/local/gcc-4.3.5
So how to I tell the build process that I want a 64 bit compilation?
