My first PKGBUILD (dosage)

Question

Hi,
I have tried to adapt PKGBUILD for orphaned app dosage (app to keep a local mirror of specific web comics) and I have made new working PKGBUILD with two errors when building:
==> WARNING: Using a PKGBUILD without a package() function is deprecated.
==> WARNING: Package contains reference to $pkgdir
so I need some basic help.
My PKGBUILD:
# Contributor: Zaplanincan <[email protected]>
pkgname=dosage
arch=('i686' 'x86_64')
pkgver=2.5
pkgrel=1
pkgdesc="A Python application designed to keep a local mirror of specific web comics."
url="http://wummel.github.io/dosage/dist/$pkgname"
license="GPL"
depends=('python-requests')
source="http://wummel.github.io/dosage/dist/$pkgname-$pkgver.tar.gz"
md5sums=('daef0c292a2a4510ba1392ec3a2e9d37')
build() {
cd $srcdir/$pkgname-$pkgver
python setup.py install --prefix=$pkgdir/usr
...and old PKGBUILD:
# Contributor: FJ <[email protected]>
pkgname=dosage
arch="i686 x86_64"
pkgver=1.6.0
pkgrel=1
pkgdesc="A Python application designed to keep a local mirror of specific web comics."
url="http://slipgate.za.net/$pkgname"
license="GPL"
depends=('python twisted zope-interface')
source="http://slipgate.za.net/dosage/downloads/$pkgname-$pkgver.tar.gz"
md5sums=('dd9550b08899d9f1904caf24888f5f38')
build() {
cd $startdir/src/$pkgname-$pkgver
python setup.py install --prefix=$startdir/pkg/usr
mv $startdir/pkg/usr/bin/mainline $startdir/pkg/usr/bin/dosage
Am I missing something else?
Thanks for the help.
