Suppressing checking of modules with pychecker

[Qopit]

Does anyone know how to stop the command line pychecker from analyzing
particular modules?  It really gets slowed down on some big ones.

In particular having 'import wx' takes a long while (30 - 60s).  If you
try pycheck'ing the program below it takes a while and prints a zillion
warnings.

#---
import wx
print "Go make a sandwich while this finishes..."
#---

I tried the blacklisting -b option, but can't seem to get it to work
right.  Plus I think it just suppresses the warnings but does not stop
it from digging through the wx module.

Anyone using pychecker with wxPython apps know what to do?
