Subject: How to find ruby?


Hi ..

I am not sure of the best way of going about finding the location of Ruby for 
a shebang line (*nix execution).

My scripts don't always have control of where Ruby might be installed (that is 
the provenance of the destination organization's sysadmin).  Some examples 
that I have run across include

 /usr/local/bin/ruby
 /usr/bin/ruby
 /opt/ruby1.8/bin/ruby
 etc.

So, what do other people normally do when they have this kind of situation 
when it comes to the shebang line?  I'd rather do it in some generic manner 
rather than have a substitution script run at install time (though that is an 
option).

Thanks,
