Thanks for the suggestion.  Unfortunately I can't install a
precompiled binary since I do not have root access on my machine.
However, I was able to compile gfortran (version 4.5.2) on my own and
it got me past my previous problems.

I have now come up with a new error.  It seems that gcc doesn't like
the option "-faltivec" (full error copied below).  A Google search
indicates that this may be an old option that isn't necessary anymore.
 How can I remove this option?  I know I didn't specify it in any
environment variable.

Thanks,
Jeremy
