Error on installing gem native extension

[stigi]

Hi there,

I just tried to install the gem via gem install ocrunner but got a compile error when building the native extension: https://gist.github.com/2634108

My configuration OS X 10.7.3 gcc -v => gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.9.00) ruby --version => ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-darwin11.3.0] gem --version => 1.8.11
