[kepler-dev] Problem fix when building Kepler via both Eclipse Ant + Eclipse Project

[Dan Higgins]

Another data point - I just timed building a completely new checkout of 
Ptolemy and Kepler using ant The time for

ant ptolemy buildkarlib run-dev

was 3 minutes 15 seconds on a 3 GHz Windows XP system
and 3 minutes 30 seconds on a MacPowerBook

On both machines, about 2 minutes was spent on compiling and jarring the 
ptolemy code.

So a 14 minute time for eclipse does seem way too long
