[Image-SIG] selftest fails, but package shows status is fine

[张诩文]

I install pil on mac os 10.6.4

I try setup.py build_ext -i, get this:

--- TKINTER support available
--- JPEG support available
--- ZLIB (PNG/ZIP) support available
--- FREETYPE2 support available
--- LITTLECMS support available


but when run the selftest.py, it's still:
--- PIL CORE support ok
--- TKINTER support ok
--- JPEG support ok
--- ZLIB (PNG/ZIP) support ok
* FREETYPE2 support not installed
* LITTLECMS support not installed


Could you help me?
