Well,  I just went through and replaced "DBD::Sybase"  with
"DBD::FreeTDS", and similar, the whole way through.

The problem is, the XS and generated .xsi refer directly to DBD::Sybase or
similar, which, in turn, requires compilation time modification (I don't
understand XS thoroughly, but, I would imagine that the package that the
XS refers to must be hardcoded in, or maybe there needs to be some
DynaLoader trickery?)

It took me about 10 minutes, since DBD::Sybase is pretty light on source
files.
