You do not need g77/f77. With gfortran and gcc from the gcc 4.1 tool suite, 
numpy and scipy compile just fine, and work very well - I am even using them 
on a daily basis for my production work! The following minimal changes should 
get everything working fine with gfortran (lines split to accomodate my 
mailer):

%build
env CFLAGS="$RPM_OPT_FLAGS" BLAS=%{_libdir} LAPACK=%{_libdir} \
  python setup.py config_fc --fcompiler=gnu95 build

%install
python setup.py config_fc --fcompiler=gnu95 \
install --root=$RPM_BUILD_ROOT #--record=INSTALLED_FILES

In general, for FC4 and above, consider using gfortran rather than g77 since 
g77 is a dead branch. Virtually everything handled by g77 is also handled by 
gfortran; see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19292 for more 
information (and ignore the flaming at the end of the comments).
