A little more information...

  cd "libImaging"
  ./configure --with-zlib=/usr/lib --with-jpeg=/usr/local/lib

I checked "ImConfig.h" and the two #define statements for libjpeg and libz are uncommented, so configure properly recognized the options.

However, when I run "make", i'm getting an error on the "jpegdecode" line:

  gcc -O -I./. -I/usr/local/include -DHAVE_CONFIG_H   -c -o JpegDecode.o JpegDecode.c
  In file included from JpegDecode.c:37:
  Jpeg.h:11:21: jpeglib.h: No such file or directory
  make: *** [JpegDecode.o] Error 1

What does this mean? Why doesn't "jpeglib.h" exist, and where is it supposed to come from?
