Use RUBY_VERSION to make that future-proof:

$ ruby19 -ve "p VERSION"
ruby 1.9.0 (2006-02-24) [i686-linux]
-e:1: uninitialized constant VERSION (NameError)
$ ruby19 -ve "p RUBY_VERSION"
ruby 1.9.0 (2006-02-24) [i686-linux]
"1.9.0"
$ ruby -ve "p RUBY_VERSION"
ruby 1.8.4 (2005-12-24) [i686-linux]
"1.8.4"
