I just implemented this strategy and while it would work for packages 
that did not bring in too many dependencies, trying to build a more 
complex package in a clean chroot failed due to the large number of deps 
installed (e.g. xine-lib brings in 88 packages). The resulting package 
list is too long to be removed in one command  (sudo: unable to execute 
/usr/bin/pacman: Argument list too long).

I don't see why this is necessary.  If building using makepkg and you 
see it fails to remove deps, then get the list from "pacman -Qtd".  If 
using makechrootpkg then just remove the "$CHROOT_SHELL/rw" directory 
and all is fixed.  I see the failure to remove the installed packages as 
a failure in pacman.  It should be able to "-Rs" chained dependencies 
and provides.  I don't like working around the true source of the 
problem.  So I doubt I will add to my initial patch - it solved the 
problem I was trying to solve and let the user know there was a problem 
removing deps which is all I think is necessary.  If someone else wants 
to add to it then go for it.

Cheers,
Allan
