 {{{
 variant python description {Builds port with python support} {
     pythonincdir=`python-config --includes | sed -e 's/-I//' | awk '{print
 \$1}'`

     configure.args-delete   --disable-python`
     configure.args-append   --enable-python  \
                             --with-python-incdir=pythonincdir \
                                                         --with-python-
