As a general rule, the GPL doesn't care what you do with your own
modified copy of something; it's only a concern if you _distribute_ a
modified copy (in which case you have to make available the source
code, etc etc). You're fully allowed to fiddle with something and
compile it for your own use, and not release your changes. See for
instance the GPL FAQ which Ben Finney posted, specifically this
question and answer:
