Log Message:
Bring this package into line with 21st century pkgsrc:

+ ZOULARISBASE is gone - just use PREFIX to find bmake
+ WRKDIR contains the name of the work directory, so find this out from pkgsrc
+ remove getcwd() calls, and use WRKDIR to find the place where the various
  informational files are placed
+ retain the ability to set the working directory from the command-line, but
  it is almost useless these days

Bump pkg revision to 2.
