 cfv works with any version of Python since 1.4 according to the website.
 Currently, macports is building it with Python 2.6, thus bringing in
 python26 when nearly everything else is built with python27. Building cfv
 with Python 2.7 will eliminate the need to keep around two Python version.

 I am providing a simple patch to make this change. There may be a more
 elegant way to allow fallback to python26 if that is the only installed
 version, but I am not a portfile expert.
