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.
Installed Xcode

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/Headers/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.
$ sudo gem install ruby-debug -v 0.10.4
