Friend lachoy is correct - DBD::Sybase does use a wider range of Client Library API calls in recent versions.

However, FreeTDS is progressing nicely so that all versions of DBD::Sybase build with the current release (AFAIK), even though some of the functionality won't work, or won't work correctly.

I try to keep an eye on the FreeTDS developpment (even though I don't actually do any of the coding myself) to keep track of the most important issues.
