Saw your message there. Imager might be a good choice for you overall, but then that isn't really what you asked. Assuming you have good reasons to want Image::Magick, then it is a fine module. I was also hoping someone with a bit more OS X experience would suggest how to solve this the "Apple Way". > I try to install the Image::Magick module.

You need to make sure the path to the .so files is included in the list above, which I would have thought they would be in /usr/local/lib based on your include path, but if they come with the dev tools in OS X then god knows where it puts them. On linux for instance there is a ld.so.conf that specifies what directories to include when looking for the shared libs. There should be something similar assuming gcc is being used. Alternatively you can specify these types of paths either in an ENV variable, LD_LIBRARY_PATH for instance, but I don't know precisely off the top of my head, usually I guess my way through it :-). > > Can someone tell me which paths I should enter to successfully compile PerlMagick? I did not find something like "ltiff" or "ljpeg", but the convert tool works fine with these formats. > You won't (likely) find an ltiff path, instead it will be libtiff.so or some such. Look for the shared lib files and see if you can add the paths to them to the above switches.
