The only license I see on the LiveCode site is at http://livecode.com/LiveCode-EULA/ and that specifically mentions that it's not GPL-compatible.
So they've dual-licensed it. The Community Edition source on Github is all GPL with this exception: https://github.com/runrev/livecode/commit/51e3958082d9edd645...
