[sf-perl] Perl host porting

Aside from mismatch module versions, and paths, it should be fairly simple
to port a script from host a to b.  My guess is that the web server
configuration is different between the two hosts though.  Sounds like in
your old host, the extension for execcgi was both .pl and .cgi, while on the
new one it's only cgi?

I'm sure there are other differences, I suggest you compare the two configs.
