trouble using RubyCocoa after Ruby update

[Yvon Thoraval]

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 ?
