I am trying to install the RMagick gem under MacOS X (10.3 latest). I have ImageMagick 6.1.8, with development headers, installed via Fink. When I do a simple gem install it seems to work, but I can’t find any dynamic library for it and neither can Ruby when I try to actually use it. The following is a transcript of the install. Note that it complains that it can’t find mkmf, but proceeds anyway. Please advise. # gem install RMagick Attempting local installation of ‘RMagick’ Local gem file not found: RMagick\*.gem Attempting remote installation of ‘RMagick’ Building native extensions.

Of course, there was one more hiccup after that. I had to manually edit the rmagick\_config.h file to not use X11 since, for whatever reason, …/include/magick did not have xindow.h. I could have done more investigation on the ImageMagick side, but I was more concerned with non-display Magick anyway so I took the shortcut. –Greg ---

If you decide to go back and get RMagick working with X11 (it’s nice to be able to use display and animate to check your images), here’s the OS X installation FAQ: [http://rmagick.rubyforge.org/install-osx.html](http://rmagick.rubyforge.org/install-osx.html) Also I’ve heard that some folks are having good luck using the DarwinPorts package. It’s a bit out-of-date (1.9.2) but may be easier to install from scratch.
