Got the DevKit installed and re-ran the ffi install….got this as an output:

C:\\Documents and Settings\\******>gem install ffi

Answer 1

Copied from another post:

As stated in Issue with installing ImageMagick and rmagick on Mountain Lion, ffi appears to be configured to look for 'gcc-4.2', so once I updated my Apple command line tools (which I may or may not have needed to do), I created a symbolic link to make the ffi install configuration happy:

sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2
