I had a problem installing the "rmagick" gem on centos. The following is the conclusion that I have. Can someone help me determine which package I am missing ? I installed all the other threads mentioned: RMagick installation error

After the following sentences, I now get this conclusion:

The output of gem_make.out is similar to the output of the terminal.
