Comment:

 I think you missed the point. The goal is that the user can modify the
 Portfile file (e.g. for testing) and doesn't need to choose the subport.
 MacPorts should do it for him if the user has typed "port destroot" only.
 Since building the stub itself is quite useless, one wouldn't lose any
 feature.

 And IMHO, MacPorts should never install a port using the modified Portfile
 if the user hasn't requested it explicitly. What I mean here is that "port
 build" in a p5-xml-libxslt directory currently has the effect to install
 and activate the p5.12-xml-libxslt subport (at least on my machine), which
 is quite an unexpected behavior (upgrading the other dependencies is OK,
 as they shouldn't have a modified Portfile).
