There may be a bug, but the way that this is *supposed* to work is that
scripts that explicitly give a Ruby version on the #! line
(/usr/bin/ruby1.8, for instance) have to depend on the ruby1.8 package,
whereas scripts that use #!/usr/bin/ruby have to depend on the ruby
package.  Depending on ruby (>= 1.8) is not correct if you use
#!/usr/bin/ruby1.8, sice ruby 1.9 may not provide that path.

Does that fit what the package is doing?
