Hmm, so that works -- the issue is where I run it as an executable
(see the end of the log)

sa  [~]$ ruby a.rb
true
a.rb:3: warning: already initialized constant FOO

sa  [~]$ ruby -v
ruby 1.8.5 (2006-12-25 patchlevel 12) [i386-linux]

sa  [~]$ uname -srm
Linux 2.6.9-42.0.3.ELsmp i686

sa  [~]$ cat /etc/redhat-release
Red Hat Enterprise Linux ES release 4 (Nahant Update 4)

sa  [~]$ chmod +x a.rb

sa  [~]$ ./a.rb
/usr/bin/env: ruby -w: Permission denied
