I’m having to setup multiple machines, and I’ve got a new problem (at least each time my problem is new … I’m not repeating the old ones) I’ve compiled ruby and installed it - I’ve put it into /usr/local/bin, if that’s a problem, I can redo it to whereever. Note that I didn’t see any errors in the ruby compile / install Next was an attempt to install rubygems. I ran ruby setup.rb ## from the directory with rubygems. It starts out OK, then I get ## /usr/local/lib/ruby/1.8/i686-linux/syck.so: /usr/local/lib/ruby/1.8/i686-linux/syck.so: undefined symbol: \_\_stack\_chk\_fail\_local - /usr/local/lib/ruby/1.8/i686-linux/syck.so (LoadError) from /usr/local/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:27:in `require' from /usr/local/lib/ruby/1.8/yaml/syck.rb:5 from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in`gem\_original\_require’ from /usr/local/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:27:in `require' from /usr/local/lib/ruby/1.8/yaml.rb:11 from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in`gem\_original\_require’ from /usr/local/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:27:in `require' from /usr/local/lib/ruby/site_ruby/1.8/rubygems/package.rb:6 ... 11 levels... from setup.rb:887:in`exec\_install’ from setup.rb:705:in `invoke' from setup.rb:674:in`invoke’ from setup.rb:1352 Either I’m missing something - or my ruby install wasn’t as clean as it looked. I looked at the source, and I thought that all I needed to do was install the yaml and syck files onto the machine (I’m running kubuntu) - but that didn’t seem to do any good. Would someone be so kind as to help here. Thanks in advance —Michael ---

I’ve installed ruby and rubygems on Kubuntu recently. No links handy off the top of my head, but Google for ruby+rails+rubygems+ubuntu. There are few sites that give very nice apt-get instructions to ensure you can correctly compile Ruby and get gems running. The default install on Unbuntu is lacking some things needed by Ruby/Rubygems. (zlib comes to mind, and I had a problem with ssh recently as well.) – James B. “Inside every large system there’s a small system trying to get out”. - Chet Hendrickson ---

I hope it helps. Cheers, Aaron K.
