I think the error is not related to Boost.Python. Did you tried to
create small executable that uses the library you wrap? I guess you
will get same error.
May it worse to take this error to ferespost developers?

Did you try to adjust LD_LIBRARY_PATH, so it will contain path to
ferespost so file?
If ferespost supports static linakge, maybe it worse to try that mode?
