error:  error installing rubyosa:     error: failed build gem native extension.  /system/library/frameworks/ruby.framework/versions/1.8/usr/bin/ruby extconf.rb mkmf.rb can't find header files ruby @ /system/library/frameworks/ruby.framework/versions/1.8/usr/lib/ruby/ruby.h   gem files remain installed in /library/ruby/gems/1.8/gems/rubyosa-0.4.0 inspection. results logged /library/ruby/gems/1.8/gems/rubyosa-0.4.0/gem_make.out 

i've had error show lot of times while installing gems. found out later needed development package included needed headers compilation. on debian machine in ruby-dev package.

i reading on internet os x ships headers xcode, might need them there.
