- Add some environment variables that need to be present when using packages

from the build cluster.  These are required to get the dependencies the
  same as the parallel builds.
- Add an optional second argument that allows you to specific an alternate
  ports directory.
- Remove the temporary file after we are done with it.
- Remove ksh93 because it won't make it on the discs until the license issues
  are resolved.
