Hi all, For those of you who build Ruby on Windows manually, but suffered from the inability to use rubygems because you couldn't get zlib to build properly, never fear! Zliby 0.5 is here! For reasons that are too pathetic to go into here, I recently had to rebuild Ruby 1.8.6 from scratch using VC++ 8. This was fine, except that it left me without zlib (and openssl, but that's another topic). Since rubygems requires zlib, this was problematic. Solution? I installed Michael's "zliby" library (renaming it to zlib.rb). Worked like a champ. Installed a couple gems via "gem install" without a hitch. The speed seemed fine, too. Awesome work Michael. Thanks, Dan
