Subject: makepkg: save path to PACMAN and test availability
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After we install dependencies, we source /etc/profile so that new
elements get added to the path. As this can override any local setting
of PATH, we store the full path of the PACMAN variable passed to makepkg.

Also, add a check for PACMAN availability if it is needed to deal with any
dependency operations.
