[Rubycocoa-talk] Re. trouble getting RubyCocoa to work

[Gavin J. <ri...@ma...>]

It appears to be environment path issues and I could get around it:

      2  23:04   cd /usr/local/lib/ruby/1.6/
     12  23:38   sudo ln -s /usr/lib/ruby/site_ruby/1.6/osx/ osx
     20  23:44   cd powerpc-darwin6.4/
     21  23:44   ls
     22  23:45   sudo ln -s  
/usr/lib/ruby/site_ruby/1.6/powerpc-darwin6.0/osx_aeosa.bundle  
osx_aeosa.bundle
     23  23:45   sudo ln -s  
/usr/lib/ruby/site_ruby/1.6/powerpc-darwin6.0/rubycocoa.bundle  
rubycocoa.bundle


and then I could run irb:
