The file RMagick2.so is present in the given path /opt/ruby-enterprise-1.8.7-2010.02/lib/ruby/gems/1.8/gems/rmagick-2.12.2/lib.

Following are the versions my application is using:-

I solved this problem on RHEL5 with the following changes:

  • Create /etc/ld.so.conf.d/local.conf

  • add the following lines:

    /usr/lib
    /usr/local/lib

  • run ldconfig

This fixed the issue for me. (On to the next dependency ..)

What Linux system is this one exactly? It seems it is missing libMagickCore.so.4. If I look in my Ubuntu, I see it belongs to the package libmagickcoreX", where theX` stands for the version. The most I've seen int he last Ubuntu is version 3, but I've seen RPMs with version 4, so in your system you may be able to install that package version.
