New description:

 Would it be possible to implement the possibility to select a default pip
 and virtualenv?
 E.g.
 {{{
 sudo port select --set pip py27-pip
 sudo port select --set virtualenv py27-virtualenv
 }}}

 Just like for python, ipython, cython or nosetests this would be very
 useful.
 pip and virtualenv are quite frequently used e.g. in shell scripts written
 by others to install software and if only pip-2.7 is on the PATH they
 fail.
 I would prefer setting the default version via Macports than via symlinks
 or aliases.
