Nope, the colon is only needed as a delimiter if you give more than 
one file.

$ export PYTHONPATH=~/src/python/
$ idle

works fine here. Where are you setting PYTHONPATH and from where do 
you run idle? If you set it in a terminal window, but run idle from 
a Desktop menu it won't work as exporting environment variables does 
only affect sub-processes. You might want to set PYTHONPATH in your 
~/.bash_profile and then re-login.

Also, how do you name your file? A Python module must end in .py
