 I do not see the issue with the ports system here, but rather with
 package managers, which do not handle conditional behaviour in ports
 well enough.
 
 There would be several solutions:
 
 * get rid completely of bin/2to3, bin/pydoc<PYMAJOR>, bin/idle<PYMAJOR,
   bin/python and so on, which is likely to break tons of ports and 3rd
   party software without a chance to ever fix this cleanly
 
 * add the symlink creation for bin/python, etc. to the existing
   meta-package lang/python (where it belongs anyways in my opinion) and
   into relevant <PYMAJOR> meta-packages lang/python2, lang/python3,
   etc., which depend on a default version (usually the latest one),
   which can be overriden by users
 
 * fix up or enhance the package managers to support the conditionals
   within the ports.
 
 I would prefer the second solution, which manages the symlink creation
 in own packages and ports.
 
 Cheers
 Marcus
