Comment (by mojca):

 Adding a new builder was precisely the main reason why I opened this
 ticket. Solving this should be pretty straightforward with a few lines of
 shell scripting (or perhaps a tiny addition to the `port` command to allow
 for easier listing of subports), only a few lines in `mpbb` need a fix.

 I don't know how to sanitize input though.
