well, it will replace masqmail-$PKGVER-$PKGREL.pkg.tar.gz if it is
installed on the system, but it won't replace
masqmail-0.2-$PKGVER-$PKGREL.pkg.tar.gz .   It will only complain
about the other version being installed if you put a
conflicts=('masqmail-0.2') in the -0.3 PKGBUILD. (and vice-versa in
the -0.2 PKGBUILD.)

Hope that clears things up.

*note* $PKGVER and $PKGREL aren't strict expansions of the variable in
the current PKGBUILD, I'm just using them in place of the asterisk
glob to prevent confusion.
