Actually, this appears to be broken when I try to use it. Example:

root@bob root # ls -l /sbin/rubyx
lrwxrwxrwx 1 root root 23 Nov 24 20:41 /sbin/rubyx -> /pkg/rubyx.1/sbin/rubyx
root@bob root # irb
irb(main):001:0> require 'pathname'
=> true
irb(main):002:0> Pathname.new('/sbin/rubyx')
=> #<Pathname:/sbin/rubyx>
irb(main):003:0> Pathname.new('/sbin/rubyx').realpath
Errno::ENOENT: No such file or directory - /sbin/pkg
