Thanks for your suggestion. I needed to do this, but it solved a different problem.

The compilation problem above appears to be caused by settings of CPPFLAGS and/or LDFLAGS that pointed to my macports installation. Unsetting these before compilation solved the compiler error.

However, the links you mentioned were also necessary. Without them matplotlib links against the system Tcl/TK in /System/Library, whereas Python's tkinter is linked to the one in /Library. This gives a clash at runtime:

"Class TKApplication is implemented in both /Library/Frameworks/Tk.framework/Versions/8.5/Tk and /System/Library/Frameworks/Tk.framework/Versions/8.5/Tk. One of the two will be used. Which one is undefined."

and a couple more of these. Thereafter it crashes. The links in /Developer/SDKs/MacOSX10.6.sdk/Library/Frameworks to the frameworks in /Library make the thing consistent.
