may be their is a third way (using symlinks) ?

not working at the time being it seems ruby isn't following symlinks

i did a :

~%> sudo mkdir /opt/local/lib/ruby/site_ruby/1.8/yt

and then :

~%> sudo ln -s direct.rb /opt/local/lib/ruby/site_ruby/1.8/yt/direct

testing this :

--- direct_test.rb -----------------------------------------------------
require 'yt/direct'

puts "$basename = #{$basename}"   ### line 3 ###
------------------------------------------------------------------------

i get :

> direct_test.rb
/opt/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`gem_original_require': no such file to load -- yt/direct (LoadError)
        from
/opt/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`require'
        from /Users/yvon/bin/direct_test.rb:3
~/bin/rb%> 


the path is correct because using :

--- ruby_libs_dir.rb ---------------------------------------------------
#!/usr/bin/env ruby -w

require 'rbconfig'
puts Config::CONFIG['rubylibdir']
puts Config::CONFIG['sitelibdir']
------------------------------------------------------------------------

i get :

~b%> ruby_libs_dir.rb
/opt/local/lib/ruby/1.8
/opt/local/lib/ruby/site_ruby/1.8

then i must conclude ruby isn't following symlinks (?) then no third
solution.

the reason, for me, using this kind of solution it's because i have two
installed ruby (apart from the one installed by default by Apple) :

one in /opt/local...  (darwinports)
another installed in my HOME fo JRuby

then , i'd like avoiding copying scripts in different locations.
