Here is the Xcode project to build Pof as a Pd external for OSX, allowing to edit Pof patches with Pd on OSX.
notice : to build OSX pof external you need to hack openFrameworks source a bit :
in the file of_v0.9.0_osx_release/libs/openFrameworks/app/ofMainLoop.h, move the declaration :
void (*pollEvents)(void);
to the public area, for example at the end of this area, after the line :
ofEvent<void> exitEvent;
