Hi Arjen:

Correction: wherever I said "packfile" above should be replaced with
"pkgfile".  (Sorry about that!) Furthermore, if you look at
<https://wiki.archlinux.org/index.php/Pkgfile> it appears that the
pkgfile functionality is now just part of the pacman package. So since
you have pacman automatically installed as part of the base packages,
then my educated guess is the "pkgfile" command should just work with
nothing additional you have to install.
