no no, you put the epatch command in your ebuild file (your own version
that you put in PORTAGE_OVERLAY.) Then the patch gets applied to the
mutt source file before compilation.

epatch is internal to portage, it is the gentoo version of the patch
command. If you want to see some examples look in portage, eg:
grep epatch /usr/portage/* -r

no. lets start again.
there are two places that portage can get the patch from.
1. If it is small you can put it in ${FILESDIR} which is, in our case:
/usr/local/portage/mail-client/mutt/files/cool-all-mutt.patch
Then it is only on your system. If your revised ebuild gets accepted
into portage then the patch file will also get in the portage tree and
every gentooista will eventually get it via emerge sync.
2. If it is large, or if it is, for example, a commonly available public
patch (for example that some third party has published) then you can
instruct portage to download it from the net by specifying a SRC_URI,
viz:
SRC_URI="http://some.place.net/pub/patches/mutt/cool-all-mutt.patch";
You can do that in your private OVERLAY ebuild, and as you say you found
the patch on the net, that may be the best way to do it.
Again, if your revised ebuild gets accepted and if the "powers that be"
get with it, the patch file might also get into the gentoo mirrors,
meaning that it is easier to get with more redundancy.
