I found a solution after all, from http://old.nabble.com/_backend_gdk-not-found-td26514059.html#a26514059 the thread I mentioned in the original post, which turned out not to be as cryptic as I had thought.
Just as the answerer there suggested, I had PyGTK but matplotlib wasn't recognizing it during build; when I tried building from source instead of using macports this was made clear in the build output. As he said, I searched my computer to find a file called pygtk-2.0.pc, and added the directory it was in to the system variable PKG_CONFIG_PATH. After I did that, the build was successful and I had no further problems! Thanks to everyone who may have read my post, but I would up figuring this one out on my own. thecommexokid wrote: > > Hi all, > > I am new to the forum and to all things PyGTK and matplotlib, so go easy on me, please. > > A colleague created a Python program that uses matplotlib and GTK. I wanted to be able run her program on my MacBook (OS X 10.6.7). I used macports to update/obtain Python 2.7, matplotlib 1.0.1, and PyGTK 2.22.0.

As I said, I am new to these things, and I don't really understand the interplay between Python, PyGTK, and matplotlib, so if there's crucial information I haven't provided, or if this isn't the best forum in which to be asking this question, let me know. > > Thanks in advance for the help. > > *** > > PS: I originally posted this question at the GTK+ Forums ( http://www.gtkforums.com/viewtopic.php?f=3&p=69969#p69969 thread ), but it seemed as though this might be the more appropriate forum.
