building NB, java.lang.OutOfMemoryError: PermGen space

I've been using MB7 with Java and Ruby clusters for debugging Ruby
and JRuby programs but I can no longer build it.

I've got an up-to-date clone of NB main and am running out of permgen
space when building on MacOS X 10.5.6. I've had this problem before
and upped the max permgen size for ant to a ridiculous level (which
worked) but now even setting max permgen to 2048 MB doesn't allow
building.

[main]$ java -version
java version "1.5.0_16"

Java HotSpot(TM) Client VM (build 1.5.0_16-133, mixed mode, sharing)

[main]$ /opt/local/bin/ant -version
Apache Ant version 1.7.1 compiled on June 27 2008
