freetds on solaris 11: symbol scope specifies local binding

Hi Everyone,

I'm trying to use DBD::Sybase which depends on freetds, which I'm
trying to compile under solaris 11.

./configure && make ends with:

Any suggestions?  I've tried various things like --disable-shared
(which works, but then causes DBD::Sybase to fail), --disable-rpath
(no effect), nightly development snapshot (no effect) running the link
commands manually, all with no resolution.

Thanks,
Justin
