Cannot load ruby-debug on a Mac OS X 10.7.3 Lion.

Not sure why the path is incorrect.

Ruby version is 1.8.7 which came standard with Lion.

Looking for the ruby.h path on the Lion system, the path’s are different.

./Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/Ruby.framework/Versions/1.8/Headers/ruby.h
./Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/universal-darwin10.0/ruby.h

./Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/universal-darwin11.0/ruby.h

What is the best approach from this point?

thanks,

    Solution: Xcode 4.3 needs to be installed and then from Xcode Preferences-General the Xcode Command Line Tools must be installed.

    Without the Command Line Tools the above errors are generated.

    Once installed, Ruby-Debug loads.
