kinda. rubyscript2exe barely works with ruby 1.9 and in order to run it has to extract all the data to a temp directory. crate which was designed to not need to extract to work, was stopped mid development 2 years ago. as for OCRA it works great but it only works for windows, and it still has to extract. I was thinking that it should be possible to compile a binary that can run with out extracting.
in any case forget it, I've decided it is better left to thouse more experienced. perhaps they will finally work on maying Ruby more deployable, there is a ruby summer of cod project for creating a ruby archive format that would serve the function of a JAR file in Java after all...
