Ruby binding to ImageMagick

I have recently update ImageMagick to ImageMagick 6.6.3-10

RubyGems Environment:

I really wonder why this error is coming. Thanks in advace.

Don't use lowercase ('rmagick'). The correct form is:

irb(main):002:0> require 'RMagick'
=> true

This installation of RMagick was configured with ImageMagick 6.6.3 but ImageMagick 6.4.5 is in use

Solution is error message which I couldn't see at very time. 1. Reactivate ImageMagick 6.6.3 (remove 6.4.5) 2. Keep 6.4.5 and install rmagick again.

Thanks guys for your inputs.
