[Image-SIG] can't build JPEG support with PIL 1.1.6

[Bill Janssen]

Odd thing going on here.  I've got libjpeg built and installed, with
include files, under /local, on a PowerPC Mac, running 10.4.11, which
means Python 2.3.5.  I unpack Imaging-1.1.6, edit setup.py to tell it
where to find libjpeg, and do the build:

wjanssen % python setup.py build
running build
running build_py
creating build
creating build/lib.darwin-8.11.0-Power_Macintosh-2.3
copying PIL/__init__.py -> build/lib.darwin-8.11.0-Power_Macintosh-2.3
copying PIL/ArgImagePlugin.py -> build/lib.darwin-8.11.0-Power_Macintosh-2.3
