This might get challenging for distributions shipping live packages or regular git snapshots.
And how to deal with distributions patching imaplib2? That might get intersting in case such a

Of course one could mention in the readme to either not patch imaplib2 or use the bundled one.
But who knows what distris do in the end ;)
