want to create a zipped file containing a number of files created at runtime that don't need to be written on the hard-drive first. Is there any easy solution for this? I know of zipruby (not tried yet) and the possibility of creating virtual files somehow (never done this) but do you know of some specific tutorial for this?

Typing gem -v in my command line gives me: /usr/bin/gem:12:in `<main>': uninitialized constant Gem::Requirement (NameError)... anyone know how to fix this?
