Biker is almost certainly right. While ActiveState distributes a binary DBD::Sybase package this will only work if you have installed Sybase's OpenClient libraries.

I believe that you can download an eval of Sybase 12.5 from www.sybase.com which should include the client libraries. That should at least let you verify that the binaries work.

However Sybase's OpenClient does not work with MS-SQL 2k (the last version it worked with was MS-SQL 7, and that required a patch from MS).

So I suspect that you may need to review your options, and that ODBC may be your best bet at this point (unless you want to try to get freetds to work on Win32...)
