Mildly.  :-)  The "compiled" or "optimized" .pyc/.pyo files mainly  
improve upon the time required to load them by the interpreter.

Anyway, to address your issue, most Python software uses a setup.py  
file which uses distutils, and that is supported by the BSD ports  
infrastructure via the USE_PYDISTUTILS option, which will call the  
setup.py with the right arguments to build the .pyc/.pyo files.  You  
can then list all of them in the pkg-plist and the right thing should  
happen from there.

If you'd like to see an example, check out one of the python ports  
which use this, such as /usr/ports/security/denyhosts; you'll see it  
listing:

%%PYTHON_SITELIBDIR%%/DenyHosts/loginattempt.py
%%PYTHON_SITELIBDIR%%/DenyHosts/loginattempt.pyc
%%PYTHON_SITELIBDIR%%/DenyHosts/loginattempt.pyo
