JPEG Support for Python 2.7's PIL Module on OS X Lion

My PIL module refuse to process jpeg image. It says that there is no decoder jpeg on my system. It's no good  since I want to process that kind of file using PIL in future, and my older iPhoto picture on my 13 inch MacBook Pro is generally in jpeg format too.

Here the snapshot

So I googling for it and found libjpeg at http://www.ijg.org/files/, download, exctract and install it using magic UNIX words ./configure, make, make install

Nugrohos-MacBook-Pro:~ nugroho$ cd Downloads/jpeg-8c/
Nugrohos-MacBook-Pro:jpeg-8c nugroho$ ./configure 
Nugrohos-MacBook-Pro:jpeg-8c nugroho$ make
Nugrohos-MacBook-Pro:jpeg-8c nugroho$ make test
rm -f testout*
