actually... i had to add:
>>> import sys
>>> sys.path.append("/home/kunal/projects/radio/softwares/wxPython-src-2.6.1.0/wxPython")
sys.path.append ("/usr/local/lib/python2.3/site-packages")

coz it couldnt find wx module (which i think shud hv been installed by
wxPython)

any help would be appreciated... thanks
