There are a few changes in glibc-2.10 that might make your software fail to build with it, please refer to my blog post [1] if you're not sure what the problem is. And no I don't usually provide emerge --info with these bugs because they are caused by glibc-2.10! Thanks, Diego [1] http://blog.flameeyes.eu/2009/05/24/c-libraries-galore
