There are several ways out there to install RMagick: via ports, package installer, etc. My advice: before you even start working on these.
1. Install ALL updates from Apple for your OSX.
2. Update XCode to the latest downloadable version.
Doing the above will save you a whole weekend and avoid weird errors like this:
.libs/libMagick.dylib must have a ‘:’ between its file names
H
1. Create a working directory, I made ~/app-src.
2. cd to this dir.
3. wget ‘http://rubyforge.org/frs/download.php/25349/RMagick-1.15.10.tar.gz’ or latest.
4. create a symlink from the current version of libMagick.so. to no version extension :
ln -s /usr/local/ImageMagick-6.3.3/lib/libMagick.so.10.0.7 /usr/local/ImageMagick-6.3.3/lib/libMagick.so
5. export the base ImageMagick directory above as LD_LIBRARY_PATH in the current shell you are going to compile in: export LD_LIBRARY_PATH=/usr/local/ImageMagick-6.3.3/
6. ./configure –disable-htmldoc (The HTML doc creation kept failing so I needed to do the above option.) NOTE: this is a double dash “- – ” in front of disable-htmldoc.
7. make
8. make install
9. irb; require ‘RMagick’. so far so good.
