Doesn't sound very Mac-specific to me. Sounds like Python is trying to
import part of a package named 'wxPython-unicode-2.8.9.1' in the
course of probing for modules and that this import epic-fails. The
error sounds wxpython-related if anything. I'd try asking the wxpython
or c.l.p mailinglists rather than here.
