Hi:

I had apparently installed the Sage-provided scripts

sage-g77_shared
sage_fortran

when Sage was under /opt to get some fortran functionality from within the  
notebook. Of course that functionality is missing with Sage under /usr. Both  
scripts are needed. See, from the notebook,

	Help -> Fast Static Versions -> Numerical Sage -> f2py

for a cut-N-paste example. This example is included (command line version) in  
inline_fortran.py, the InlineFortran class under site-packages/sage/misc. The  
sage-g77_shared script calls sage_fortran and sage-g77_shared is hardcoded in  
the InlineFortran class. I suppose it is somewhat awkward to have these two  
scripts, but thought I would point out that some functionality is missing  
without them. Perhaps there is a better way, without messing around with the  
InlineFortran class, to achieve the same result.
