and propose building (or even rebuilding) ports with more sensible

Could you elaborate or give an example?

To complete the above example, someone who has mpd installed without
flac support one day installs the flac port and would be recommended
to rebuild mpd with flac variant.

I realize it may not be trivial or realizable in short term but, like
you say : ports should build out of the box without too much user
configuration. It would definitely be useful to recommend variants
because currently in order to install a port I am typing "port info",
checking which variants are useful according to what's already
installed and what I want and then "port install ...". That's when I
am not lazy because most of the time I feel confident that ports build
ok and then realize I have to rebuild it because some variant was
missing.

It would be much simpler if just before installation a recommendation
like : "the ports installed on your system recommends adding these
variants : +flac +aac" (when installing mpd)

And when installing  flac , at the end of installation another message
like : "you may want to rebuild or install these ports : mpd+flac,
abcde+flac, " etc

Would running into collisions be easily solved with that "we recommend" messages? For example, some program may want PHP +apache2 and another could want PHP +no_web. Should the recommend message also explain how to switch between two versions of a port on their system (deactivate/activate)?
