I've installed the GraphicsMagick and the gem on the local machine which runs the rails server, and it worked well. However, on the dev server, the environment is setup using Passenger and Apache. I've installed the GraphicsMagick and did a bundle install. It did install the gem successfully.
However, when I access the site, I am getting the following error:
There was an error while trying to load the gem 'graphicsmagick'.
Gem Load Error is: Permission denied @ rb_sysopen - mkmf.log
Backtrace for gem load error is:

Any idea why this is happening?
The problem was that the user running the app didn't have sufficient permission to run find_executable nor write access to create the mkmf.log log file.
Adding a usergroup with sufficient access to the user solved the issue.
