I do not think this is good idea. The machine or environment where
the port is built sometimes (or, in my setups, quite often) is not
the same as where it is run. Your proposal gives a tool to tightly
tie the ports to build environments, that is detrimental for some
setups, and also diminish the value of packaging. IMHO.
