Yes, this is a total swamp. I suggest you read this: http://autopackage.org/docs/devguide/ch07.html It's a little out of date, doesn't cover all the issues, is inaccurate in places etc but AFAIK it's the only documentation on this stuff that exists. The issue is likely to be not so much gcc4 as glibc, though gcc can cause occasional issues as well. If you only want to go back one revision of Fedora though you should not encounter any of them. You can use the apbuild tool to automatically fix many of these problems. thanks -mike
