Hi

Im trying to instal gridflow for pd/jmax but I get the following error message

You need Ruby 1.9 to run GridFlow.

Ive downloaded ruby-dev via cvs:
cvs -z4 -d :pserver:anonymous@cvs.ruby-lang.org:/src co -r ruby_1_8 ruby
But I still get the error message, can anyone point me in the right direction?

Kind Thanks
