I've searched the Debian FAQ and the mailing list archives but am having no luck even though I'd bet a zillion dollars that this question has been asked before...
How do I upgrade a single package and it's dependencies from the stable versions to a less stable version like testing? I'm running a plain potato system but I want to install Sylpheed which is not available in stable. I tried downloading the .deb package and installing it but of course it then wanted a newer libc, etc. etc. Is there an easy way to use Slypheed without completely upgrading my system to testing or unstable? The system in question can not afford downtime.
