The page says MPAB is to be downloaded from the attachment on that  
wiki page. Why not put it in the repository somewhere, like in /users/ 
blb?

Does MPAB just try to build the port with its default variants, or  
does it try all permutations of variants the port will accept? I  
imagine it's not uncommon for maintainers to test a new version of a  
port with the default variants but forget (or not have the time) to  
test all variants, so variants might break over time. Patches only  
added in variants might need to be updated. Some variants might  
conflict with one another but the maintainer may not have marked  
that. Etc.
