Jim,

FGS is currently 32bit only.  I suspect what is happening is that your
system python is being used for your script, intead of the python included
with FGS which is 32bit.

What do you have as the #! line at the top of your .py script?

I did a python mapscript application on top of FGS, but as it happens
I had a bash shell script as a wrapper which explicitly did
"python myapp.py" as it's last line which picked up the FGS python since
that was first in the path.  But if you script starts with something like:

#!/usr/bin/python

then of course the wrong python will get used.  I normally prefix my
scripts with:

#!/usr/bin/env python

which I gather picks up the first python in the PATH.   I just tried
putting such a script in my fgs/www/cgi-bin directory on my AMD64 system
and it works fine - so that seems like an angle.  Let me know if it helps.

Best regards,
