These addon libs are not installed by default on Mac OS X. They come with e.g. X11 and GTK+ and are usually not symlinked to the standard libs. That's just a different habit than on Linux. I guess that's because many Mac OS X software packages will use the system software instead. Of course, that makes such software more difficult to port.
As a side bar, I will note that software that uses X11, doesn't usually have the native Mac OS X look. GIMP for OSX http://gimp.lisanet.de for example no longer uses X11 as of version 2.8
So, to be sure I understand: GIMP-2.6.12-SnowLeopard-Lion.dmg the last which uses X11, contains 2.hfs/GIMP 2.6.12 SnowLeopard Lion/Gimp.app/Contents/Resources/lib which contains the libjpeg.dylib libpng.dylib and libtiff.dylib we need as addons in grx. Where the content of this /lib will go when installed ? not to /usr/lib ? not even symlinked to there.
Specifically to Karl-Michael: where these addon libraries are actually in your system ? What are the symlinks ?
