2.4 came out about the same time as SP2. If the .pyc files worked with 2.3, I am pretty sure they will not work with 2.4 since I am pretty sure the marshal format (used to make .pycs) was changed slightly for 2.4 after no change for a few releases. It will change again for 2.5. Python is intended to be distributed as readable source. .pycs are intended to be temporary caches, only kept around to avoid recompiling with every run, but certainly disposable with version changes.
