Searching on google tells me something like so:

     http://macosx.forked.net/bbarchive/forum1/000033.html

  "You need to create a dynamic library. add -fno-common to your
  linking (check the compiling docs on fink.sourceforge.net it covers
  this)"

So I looked up the fink docs and found this:

     http://fink.sourceforge.net/doc/porting/shared.php

Looks like there is a distinction between loadable modules and shared
libaries on OSX.  The page cited above has more details on how to
build a shared module or a dynamically loadable module.  The last
section in that page tells you how to build a loadable module.  You
will need to change the way the libvtkRenderingPythonTkWidgets.so is
built accordingly.  I guess everything should work fine if that is
done.

Good luck!
