I was worried that it was an IO issue with macruby, which is why I am very excited that the 0.5 version is going to be address the IO system--hopefully it will help with this issue. I would love to help, but an issue spanning macruby, obj-c, sqlite3, and possibly C is really stretching my abilities.
On the subject of sqlite wrappers in objective-C. I tried several that I found on the sqlite webpage (the have a long list of wrappers in several languages including obj-c). But it appears that most if not all are not being maintained and are not up to date and don't work with Leopard. If anyone knows of a light weight obj-c wrapper for sqlite3 that works in Leopard, please let us know. If I had some code that works to look at, I should be able to adapt it for macruby. framework 'QuickLite.framework' # fails with the error below framework 'QuickLite' # fails can't find file Error Domain=NSCocoaErrorDomain Code=3585 UserInfo=0x800621ae0 "The bundle “QuickLite” could not be loaded because it does not contain a version for the current architecture."
