Comment 1 for bug 956272

Did you get exiv2 and pyexiv2 from official packages for Centos, or did you compile them yourself?

For the record, according to c++filt, the undefined symbol is:

    Exiv2::Iptcdatum::record() const

This issue looks vaguely familiar, a similar problem was reported at http://dev.exiv2.org/issues/627. However Iptcdatum::record() is not virtual.
