Comment (by ken.cunningham.webuse@…):

 This was useful (from Jeremy Hu)
 {{{
 which installed ports are using c++:

 grep -R 'c++' /opt/local and port provides .. ? =/
 }}}

 that gave a moderately long list of files, from which it wasn't too hard
 to do
 {{{
 port provides XYZ
 }}}
 and figure out which ports they belonged to.

 In the end, on my system with hundreds of ports installed, it all came
 down to less than a dozen c++ ports, although it took 1/2 an hour to
 figure them all out. That was much faster than just bulldozing the whole
 installation, however.
