ofxBullet Simple Example, no member 'cacheMatrices' in 'ofCamera'

I’m trying to compile the ofxBullet Simple Example https://github.com/NickHardeman/ofxBullet in XCode, OS X 10.8, openFrameworks v0073, and I get a single error that says “No member named ‘cacheMatrices’ in ‘ofCamera’”. What the heck? Was cacheMatrices() removed in v0073?

this was apparently already removed in 0071 (https://github.com/openframeworks/openFrameworks/commit/09ee85b159f46463e4d840d9df59558663a29891), during the ofcamera refactoring apparently.

The code will compile fine if you uncomment that line. All the examples will compile fine but i’ dont know if it can be the source of a possible hidden problem.
