Before installing the sybase package you suggested, I did another test with
a different sybase package (sybpydb) we had installed.

RuntimeError: no driver available Sybase
As you can see, the connection works with the package sybpydb, but not with
DAL.
Do I need a different adapter in web2py/gluon/packages/dal/pydal?
What's missing here to make DAL work with Sybase?
Why installing the Sybase package you suggested would make a difference
when using DAL?
I would imagine that the Sybase package you suggested should work similarly
to sybpydb, right?
I would greatly appreciate any help and suggestions to make this work.
Thanks,
EF
