Summary and Info:

consider this PKGBUILD:

---- start

pkgname='test'
pkgver=0
pkgrel=0
arch=(any)
pkgdesc='just a PKGBUILD demo'
url='archlinux.org'
license=(custom)

depends=(perl-xml-xpath)
makedepends=(boggggussss)

package() {
touch $pkgdir/test
}

---- end

which has a normal entry in depends=() and an unresolvable entry in makedepends=().
running `makepkg -fcrs` installs the depends=(), then tries to install the makedepends=() and fails.
But it also fails to uninstall perl-xml-xpath which got installed as depends=().

The reason is, that makepkg does not update the "current_pkglist" variable between installing depends=() and makedepends=() (and checkdepends=()).

The following patch solves the issue:

---- start

--- a/scripts/makepkg.sh.in
+++ b/scripts/makepkg.sh.in
@@ -1366,6 +1366,10 @@ else

+ fi
+
if (( RMDEPS && INSTALL )); then
original_pkglist=($(run_pacman -Qq)) # required by remove_dep
fi

---- end

I experience this with makepkg for quite some time now (I'm unsure if it was better at any time), most recently with pacman-5.1.3-1.

P.S.: How is one supposed to compile/test with the git HEAD of pacman? Running `sudo make install` inside the git repo (after building with make) killed my pacman ... (I was used to install modified devtools versions into /usr/local with this command)
