Hi! I was trying to install ruwiki via gem. C:\temp\rubygems\rubygems-0.8.1>gem install ruwiki Attempting local installation of 'ruwiki' Local gem file not found: ruwiki*.gem Attempting remote installation of 'ruwiki' ERROR: While executing gem ... (Zlib::BufError) buffer error C:\temp\rubygems\rubygems-0.8.1>gem --version 0.8.1 C:\temp\rubygems\rubygems-0.8.1>ruby -v ruby 1.8.2 (2004-07-16) [i386-mswin32] Thinking that it might be some broken dowlnoad issue or something, I downloaded the file myself and tried to install it locally. C:\temp>gem install -l ruwiki-0.9.0.gem Attempting local installation of 'ruwiki-0.9.0.gem' ERROR: Error installing gem ruwiki-0.9.0.gem[.gem]: buffer error Strangely enough I can manually unpack the .gem file using shareware WinRAR just fine. The included .gz files don't seem corrupt, either; I could unpack them. Then I went for the manual installation, which worked fine, except one failure in one of archive-tar-minitars unit tests C:\temp\archive-tar-minitar-0.5.1>install Checking for test cases: Loaded suite Unnamed TestSuite Started .F...................
