This reminds me of a script I've been working on to remove unnecessary
cruft. Everything that follows is run as root, because it runs
"emerge". The attached script "autodepclean" parses the output from
"emerge --pretend --depclean" and generates a script "cleanscript" that
you can run to clean up your system. This should handle your situation,
but it's also a general solution to the entire class of problems of
cleaning up when you remove all programs or USE flags that pull in a
lib. It is not restricted to just HAL
Warning, this script is beta. Use with care. It will remove
gentoo-sources versions higher than your current kernel. This is
technically correct for removing unused ebuilds. But it may not be what
you want.
