I find the issue came from the matplotlib backend. The problem is gone when using TkAgg backend. However, TkAgg doesn't work with matplotlib 1.3.x, which has some conflict of Tk dynamic library due to different Tk version, i.e., macports uses Tk8.6 and Mac OSX 10.8.3 uses Tk8.5.
I really need the "tri" package in matplotlib 1.3.x. Is there anyway I can manually replace the "tri" package in matplotlib 1.2.0 (installed by macports) with the one in matplotlib 1.3.x (downloaded from the latest master in github repository?
