framework replacement

Subject: framework replacement

I'm trying to work around a problem where the latest update of Mac OS X (10.5.8) has a broken XQuery.framework. I've discovered that replacing the XQuery.framework on Mac OS X 10.5.8 with a version from Mac OS X 10.5.7 solves all the problems.

I'd like to embed the XQuery.framework from Mac OS X 10.5.7 in my application and force it to be used over the faulty system version on Mac OS X 10.5.8. I've managed to get it into the application bundle and setting the environment variables DYLD_PRINT_LIBRARIES and DYLD_PRINT_LIBRARIES_POST_LAUNCH show that it's being loaded but it doesn't appear that the framework is being used. GDB also shows that the symbols are loaded, I can create breakpoints on functions in the XQuery.framework. I'm wondering why when I call -[NSXMLNode objectsForXQuery:error:] it doesn't call out to the corresponding functions in the XQuery.framework unless it's been loaded from /System/ Library/PrivateFrameworks?

Anyone know how I might be able to get this to work?
