I blew away Octave.app and reinstalled, and now Octave seem to be  
getting the location of ImageMagick correctly. However I still am  
having problems installing the Image package. The error messages I  
get now are:
1) /usr/bin/ld: warning can't open dynamic library: /tmp/dependencies- 
i386/lib/libz.1.dylib referenced from: /Applications/Octave.app/ 
Contents/Resources/lib/octave-3.0.3/liboctinterp.dylib (checking for  
undefined symbols may be affected) (No such file or directory, errno  
= 2)
/usr/bin/ld: Undefined symbols:
_CloneImageInfo
_DestroyImageInfo
_GetExceptionInfo
_ReadImage

2) A number of messages that seem to be benign and not shown here.

3) error: called from `pkg:configure_make' in file /Applications/ 
Octave.app/Contents/Resources/share/octave/3.0.3/m/pkg/pkg.m near  
line 1248, column 2

Of course I still can't read in a image of "lena".

Can you tell what is happening?
