Unfortunately, that's not always a possibility. I've bugged at least one
upstream about non-versioned sources. How does one work around that if
they won't fix it?

That introduces a problem of redundancy. In some cases, more than one
package will use a given set of sources, and it will need to be fetched
and stored once for each package. Perhaps defaulting DIST_PREFIX to ""
and allowing it to be used for workarounds in the odd cases could work.

Just for the sake of demonstration, the following should show a list of
the source files which are used multiple times on any given system and
how many times they are used:

	emerge -p --fetch-all-uri --emptytree world 2>&1 1>/dev/null |
		sed -e '/^$/d;s/.*\///' |
		sort | uniq -D | uniq -c | sort -n
