Just remove all your pyc files as part of the update/install process.  You
shouldn't ship pyc's anyway.

In a batteries-included setup like Python, the installation process (at
least on Unix) winds up compiling lots of files I will never use, so I
occasionally go through and wipe out all my py[co] files anyway.
