metaprogramming

It is said that Ruby is a metaprogramming language. I wonder if the first 3 lines can be made less verbose using metaprogramming?

RUBY_VERSION ||= "unknown version"
RUBY_PATCHLEVEL ||= "unknown patchlevel"
RUBY_PLATFORM ||= "unknown platform"

print "Ruby ", RUBY_VERSION, " patch ", RUBY_PATCHLEVEL, " on ", RUBY_PLATFORM
