Hi, > http://www.fmod.org/files/fmodapi375win.zip thanks for pointing this out! The FMOD team sure had a bad timing for a website redesign. I check if including fmod.dll in the gem is okay, to avoid this annoying manual downloading. > C:\ruby\lib\ruby\gems\1.8\gems\gosu-0.7.4-mswin32\examples>ruby CptnRuby.rb > CptnRuby.rb:36: Gem is not a class (TypeError) Whoops, name clash. As a hotfix, you can edit CptnRuby.rb and replace every occurence of 'Gem' with 'CollectibleGem'. Sigh. I hoped it wouldn't be so obvious how new the Gem package is. :) Thanks a lot for your bug reports! Julian
