“rmagick” gem installation issue

Question

I am having issue while trying to install \"rmagick\" gem on centos. Following is the output I am having. Can anyone please help me identifying what package I am missing

Answer 1

It doesn't look like you're missing any packages. The error message is important:

Perhaps you should add the directory containing `MagickCore.pc' to the PKG_CONFIG_PATH environment variable
