I think the standard approach when using packages is to report the bug to
the package maintainer. In particular, nobody but him know what version/CVS
date that package corresponds too.

Why should unit_test_framework define such a symbol? Especially 'weak'? If
you link to libboost_unit_test_framework you are supposed to provide
init_unit_test_suite function in your application, no? Do you provide one?

For details, here's output from 'readelf -W -a <unit_test_lib.so>' where the
lib is produced with Boost.Build V2:

 917: 00000000     0 NOTYPE  GLOBAL DEFAULT  UND         
                          _Z20init_unit_test_suiteiPPc

The symbol is underfined, not weak. And I get no link error for
test/example/unit_test_example1.
