Continuously have problems installing rdiscount under Jruby on Mac OS X 10.7 with the Apple Developer Tools.
LD linked library error regarding not being able to find -lbundle.o
The cc compiler is using /usr/local/lib and bundle.o is instead in /usr/lib
The below adds /usr/lib as a path the compiler will check for shared libraries
gem install rdiscount -- --with-ldflags="-R /usr/lib"
