CC'ing Ludek Smid.  Ludek, Brew reports the following when I try to build:

$ make build COLLECTION=dist-2.1AS-errata-candidate
(cd ../common && cvs update)
cvs update: Updating .
Usage: brew build [options] target URL
(Specify the --help global option for a list of other help options)

brew: error: Destination tag dist-2.1AS-errata-candidate is locked
make: *** [build] Error 1

Where should I build candidate packages for these NZ timezone updates?

IBMJava2-JRE-1.3.1-14 built into dist-2.1-maint-candidate.
