Thanks Michael, that worked just fine. Since Ubuntu 8.10 is pretty
standard for linux-newbies, here are exactly the steps I did after the
crash (if someone googles the same error I got).
>make clean
>export SAGE_FORTRAN=/usr/bin/gfortran
>export SAGE_FORTRAN_LIB=/usr/lib/libgfortran.so.3.0.0
>make
>make test
----------------------------------------------------------------------
The following tests failed:
sage -t "devel/sage/sage/finance/time_series.pyx"
Total time for all tests: 5662.6 seconds
