Cela faisait bien longtemps que je n'avais pas rencontré de bug dans l'excellent fink que j'ai été très surpris de ne pas pouvoir installer Imagemagick sur mon PowerBook Pro. Je ne me suis pas laisser démonter et j'ai immédiatement ouvert le bug qui va bien.
Le message d'erreur que j'obtient est le suivant :
The following 4 additional packages will be installed:
ghostscript imagemagick-shlibs xfree86 xfree86-shlibs

WARNING: if you compile X11 applications against this XFree86 release,
you will *not* be able to run them if you decide to revert to Apple's
X11 provided with the OS.
You have an existing X11 installation in /usr/X11R6 and/or /etc/X11.
This package refuses to overwrite these. Remove them, then tell Fink to
install xfree86 again. (The package won't be recompiled.) If you want
to keep your X11 installation, please see the FAQ entry at
http://fink.sourceforge.net/faq/usage-packages.php#apple-x11-wants-xfree86
for more information on how to configure your system.
Press Return to continue.

La solution est toute simple il suffit d'installer le pkg user.X11 qui se trouve sur le DVD apple, et le X11 sdk qui se trouve sur le disque des outils de developement.
