Fix the version test for p5-SDL, so that this at least continues
to build after the recent update of p5-SDL to 2.1.2. Note that
I've only compile tested this with the new p5-SDL; I'm not in a
position to test it more fully right now.
Changes:
Nearly exactly one year after the first ever release of Frozen-Bubble, the
team strikes back with a new release providing major features enhancements:
* a level editor has been added
* the 1p-game now comes with 100 levels (instead of 50)
* all the graphics have been re-designed
* the 2p-game features the chain-reaction mechanism (as an option)
* manual pages (from Debian)
