Thank you very much for your hint! On second thought i remembered to

:-) Yes, and a lot of people will have done the same kinds of things
(I have quite a bit of Open Source software installed on my machines).
But please allow me one additional question (if you haven't realized
by now that i am a total amateur you'll probably do that now): If i
cut off ImageIO from the libs in /usr/local/lib by deleting the
symlink
and replacing it with an empty directory - will it not crash/
complain or
at least be somehow unhappy? Obviously, i am not understanding
something
here - but i'm quite anxious to learn it!
It won't crash or complain, no. All that's happening is that the new
linker is finding copies of libjpeg et al. in /usr/local/lib before it
finds the ones that are in the ImageIO framework. If you replace the
symlink with an empty directory, it won't find anything in /usr/local/
lib (since the SDK redirects it to /Developer/SDKs/MacOSX10.4u.sdk/usr/
local/lib, which will now be an empty folder rather than a symlink to
the real /usr/local/lib), and as a result, it will use the copies in
the ImageIO framework like it is supposed to.
I've done exactly what I suggested on the machines I use.
Kind regards,
Alastair.
