matplotlib, gtk, and libpangocairo problem

[Dexter Douglas]

Hello,

Thanks!

I ran 

sudo port -ncuf upgrade py25-gtk
sudo port -ncuf upgrade py25-matplotlib

This solved the problem!


By the way, I ran 
"port provides /opt/local/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/gtk-2.0/gtk/_gtk.so"

to see what port provides this library since it was the one referring to the libpangocairo library.  It said 

/opt/local/lib/python2.5/site-packages/gtk-2.0/gtk/_gtk.so is not provided by a MacPorts port.

Thanks.
