[Gimp-developer] OS X GIMP configure can't find JPEG library

[M Gagnon]

You will very likely need to fiddle with environment variables to help 
configure find it.
Especially check PKG_CONFIG_PATH

The following document 
(http://wiki.gimp.org/gimp/HowToCompileGimp/MacOSX), even
though it was written to be used with native GTK and not macports, can 
probably contain
good ideas of what it can look like
