Hey all, last week i did a ruby update using DP (should we say MP right now :-)) of Ruby, here is my setup : Mac OS X 10.4.8 ~%> ruby --version ruby 1.8.5 (2006-08-25) [powerpc-darwin8.8.0] ~%> gem --version 0.9.0 ~/Desktop/rb-appscript-0.1.5%> port --version MacPorts 1.320 after a successfull build of a WebKit/RubyCocoa app, then when launching it under XCode o got : opt/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require': no such file to load -- rubycocoa (LoadError) from /opt/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `require' from /opt/local/lib/ruby/vendor_ruby/1.8/osx/webkit.rb:14 from /opt/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require' from /opt/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `require' from /Users/yvon/work/RubyCocoa/DOMTreeView/build/Release/DOMTreeView.app/Con tents/Resources/DOMDataSource.rb:12 from /opt/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require' from /opt/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `require' from /Users/yvon/work/RubyCocoa/DOMTreeView/build/Release/DOMTreeView.app/Con tents/Resources/rb_main.rb:18:in `rb_main_init' from /Users/yvon/work/RubyCocoa/DOMTreeView/build/Release/DOMTreeView.app/Con tents/Resources/rb_main.rb:17:in `each' from /Users/yvon/work/RubyCocoa/DOMTreeView/build/Release/DOMTreeView.app/Con tents/Resources/rb_main.rb:17:in `rb_main_init' from /Users/yvon/work/RubyCocoa/DOMTreeView/build/Release/DOMTreeView.app/Con tents/Resources/rb_main.rb:23 the apps i want to test on my box are from "RubyCocoa Resources" <http://www.rubycocoa.com/rubification-central/1#page1> projects named "DOMTreeView" and "Downloader" another project failed to run, under command line found in "Cocoa Magic for Gruff Graphs" <http://www.rubycocoa.com/cocoa-magic-for-gruff-graphs> here is the trial : ~/Desktop/gruff-0.2.4%> ruby /Users/yvon/Desktop/gruff-0.2.4/test/test_line.rb opt/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require': no such file to load -- rubycocoa (LoadError) from /opt/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `require' from /opt/local/lib/ruby/vendor_ruby/1.8/osx/cocoa.rb:11 from /opt/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require' those probs arroses only apfet DP/MP update of ruby. may be this is as simple as moving a folder to another one, because the old install of rubycocoa/rubygems are lying under the old version of ruby, may be a good solution to cure that would be to re-inctall both rubycocoa and rubygems under the new ruby installed by MP|DP ??? in which case i'd like to know how to clean up DP|MP xithin my box because for example i have : %> port installed apache2 @2.2.0_0 apache2 @2.2.2_1 apache2 @2.2.3_0 (active) i think it is at leasst unusefull the let the apache2 old versions on my box rather more or les "dangerous". then how to uninstall an old versio after a successfull install of a new one ?
