Yes, because libpython2.2 is not looked by the system_info.py script, it
is not its job, it is an issue of distutils or scipy_distutils, I think.

Actually, the needed library path seems to be defined in 
build_ext.finalize_options method in distutils/command/build_ext.py.
I have little idea why it is not used. But try to uncomment lines
#67 and #70 in file scipy_distutils/command/build_ext.py.
I would be then interested to see the resulting linking command,
whether it will be succesful or not. 

Also print self.library_dirs in that method to see whether the needed path
is there.
May be it is enough to add the following line 

  self.compiler.library_dirs.extend(self.library_dirs)

before the call in line #84:

  res = old_build_ext.build_extension(self,ext)

Let me know how it goes.
