 Hi. I've been using macports for several years. I just wiped a mac and
 reinstalled everything. SO this is a clean macports installation.

 First I installed Unison, and that worked. Then I tried to install '''py-
 matplotlib''' and got this very strange dependency set:
 {{{
 --->  Computing dependencies for py-matplotlib
 --->  Dependencies to be installed: freetype libpng py-configobj python24

 }}}
 ...
 And you know what? It didn't work:
 {{{

 activation.

 Just doesn't seem to me that this should happen...

Comment(by blb@…):

 Unless there's a specific need for python 2.4, why not use py27-matplotlib
 (and hence, python 2.7) instead?
