Hmm...having a spot of trouble; can't seem to get past my comments:

~/antlr/code/examples-v3/java/ruby $ dump-ruby.rb ../extest
/usr/local/bin/dump-ruby.rb: line 6: require: command not found
/usr/local/bin/dump-ruby.rb: line 7: require_gem: command not found
/usr/local/bin/dump-ruby.rb: line 9: syntax error near unexpected  
token `('
/usr/local/bin/dump-ruby.rb: line 9: `def parse( text )'

#!/usr/bin/ruby

# Build, compile, and run each example in this dir.

# Each dir must have at least one .g file and an input/output pair so
