Deleting python compiled files

[ros]

Hi,

Working in a port using python i'm facing this problem. If I run the 
application after the install the py source files are compiled in pyc 
(or pyo) files. This is good cause precompiled files provide better 
performances.

The problem is deleting the port. The pyc files aren't registered in the 
pkg-plist so the deletion isn't complete and I can't delete the main 
directory containing the application files.
If I add the pyc files, when I remove the port I receive an error saying 
the checksum dosn't exist, and that's righ.
So what's the best way handle this problem ?

Thanks for your help (again)
