Qtruby and distributing applications

i am currently looking into GUI libraries for cross platform ruby
development. the question i have is… if i use qtruby to develop my
application, how do i distribute it? is there a way that i can package
it up for SIMPLE consumption by osx/lin/win users?

it seems like all the information on qtruby is very dated, and not not
very active anymore. is this the case?

my development platform is osx…
