Since coin-or-lemon has been sitting around for a while, has positive
karma, and is a new package, I went ahead and marked the F20 version
stable.  Unless there's specific demand for the F19 build, I'll let it
linger in updates-testing until the full week is up.  The F19 version
is a bit crippled, too -- it's missing some of the LP features due to
unavailable dependencies.

FWIW, coin-or-lemon (like many packages, I suspect) builds quite
quickly but has expensive tests.  --nocheck should solve your problems
if you need to rebuild things like that.
