I've just updated to Maverick, and experienced some issue with Rmagick. I've already try those solution but none of them worked
RMagick error after installing OS X Mavericks
Rmagick errors when running Rails S after upgrading to OSX Mavericks 10.9
Xcode 4.4 and later install Command Line Tools
I've already uninstall/reinstalled rmagick, imagemagick, xcode and command line tool about hundred time, but nothing worked so far..
Here's the error
Building native extensions. This could take a while...
