It's an issue with the way that pybliographer and/or some of the 
libraries it depends on were linked together.  It's not an issue 
specific to Python, it's just that lots of software that hasn't been 
properly ported to OS X yet assumes that there is a "flat" namespace, 
where on OS X it is two level (unless bastardized into using one level 
namespaces, which is more of a hack than a solution).  Fink's Python 
2.2 build probably included one of these flat namespace bastardizations 
("-flat-namespace -undefined suppress").  On Panther you can do it in a 
less-hackish way with "-undefined dynamic_lookup", but the real 
solution is to just link it together properly.

Perhaps someone who's familiar with the linker can take a look at this? 
  I'm going on vacation Thursday so I don't know if I will have time.
