Hi Jean-Denis, I can't answer your question directly but I may be able to help a bit. I also want to use mysql with `MacRuby. I tried mysql gem version 2.8.1 and hit problems I couldn't work around. I also tried ruby-mysql 2.9.4. I did get that to work after some mods, but it was very slow to load and didn't seem totally reliable.
I then decided to use an Objective-C framework that accesses SQL. Sequel Pro contains such a framework called MCPKit and it's open source. This means no gems so it loads v quickly. However, the version of MCPKit that I downloaded had manual memory management so wouldn't link with a MacRuby app. I don't know much about Objective-C but I thought I would just try recompiling MCPKit with ARC and garbage collection. To my surprise and delight it worked. I'm afraid I don't know how robust this approach is likely to be. Maybe I've just been lucky. It would be interesting to hear from someone who understands memory management better than me.
