This error started after to upgrading to boost 1.40.0_1, from 1.40.0_0
Downgrading to 1.40.0_0 fixed the link issue.
Any insight what's causing this?
One posting I googled claimed it was caused by C++ visibility issues,
and recommended adding a compile flag "-fvisibility=default", which
didn't seem to fix this issue.
