npth-config not installed by package
'make install' does not install npth-config. It's provided by upstream, so, please add this (or similar) to package() function.
install -vDm 755 $pkgname-$pkgver/npth-config -t "$pkgdir/usr/bin/"
Needed by some packages to build with npth library (e.g. The next release of gnupg or git head requires this to build).
thanks!
