-----------------------------------+----------------------------------------
 I just installed py26-matplotlib with the Qt4 backend using the following
 command

 {{{
 sudo port install py26-matplotlib +qt4
 }}}

 However, this doesn't work. Running one of the examples provided:
 {{{
 $ python /opt/local/share/py26-matplotlib/examples/user_interfaces
 }}}
 returns the following error:
 {{{
