I can only guess that maybe you don't have the gcc-fortran package installe=
d=20
(might be called gcc-g77 in suse10.1; in suse 10.2 it's called gcc-fortran)=
=2E=20
To be sure, you'd have to look into the config.log file at approx. 66% into=
=20
the file where these actual error messages are. Maybe it simply says "g77:=
=20
not found" or "-lgfortran: not found" similar, which simply means there is =
no=20
fortran compiler or its library available.
