I am struggling trying to get -ljpeg support on Mac OS X (Lion).  I can
build Emacs without graphics support just fine using XCode4 support but I
would now like to add some of the helpful additions that come with graphics
and image support.  My first attempt was to use MacPorts and install the
jpeg package.  I moved the jpeg include and lib files into /usr/include and
/usr/lib but configure still fails to detect jpeg support.  Before I try to
grok the autoconf script I am curious to know what approach is used by those
who do build on and for Mac OS X hardware to achieve graphics and image
support.

Thanks,
