Creating a separate miniruby is of course an option, although I'm not  
sure it would be needed. Why did you come to this conclusion?

Ah yes, this is because ./mspec/bin/mspec is a frontend script to the  
various runners, such as ./mspec/bin/mspec-ci and ./mspec/bin/mspec-run.
Based on the --target given to mspec the runners will be ran with the  
correct bin.

In our case the target, ./miniruby, is set by the ./spec/frozen/ 
macruby.mspec script. So to run the same set of selected specs on a  
different ruby you just use the correct mspec config script, for  
instance ./spec/frozen/ruby.1.9.mspec or give the --target option as  
r19 to ./mspec/bin/mspec

I hope this was a bit clear?
