Open Build Service: PKGBUILD complains: nothing provides perl

I am trying to get Open Build Service to accept this PKGBUILD: ~~~ # Maintainer: Ole Tange pkgname=parallel pkgver=20200622 pkgrel=2 pkgdesc='Build and execute shell command lines from standard input in parallel' arch=('any') url='https://www.gnu.org/software/parallel/ ' license=('GPL3') depends=('perl' 'procps') source=(https://ftp.gnu.org/gnu/$pkgname/$pkgname-$pkgver.tar.bz2{,.sig}) sha256sums=('41ce2f31b7850ad86b88dc756faf78a70e4ae92f45fa6603b7d108148ebe6513' 'SKIP') validpgpkeys=('CDA01A4208C4F74506107E7BD1AB451688888888') prepare() { cd parallel-$pkgver } build() { cd parallel-$pkgver ./configure --prefix=/usr make } package() { cd parallel-$pkgver make DESTDIR="$pkgdir/" install } ~~~ But it complains: nothing provides perl, binutils, procps, gcc, ... I imagine I need a line that says: Please provide me with basic build dependencies. You can see it "live" at: https://build.opensuse.org/package/show/home:tange/parallel What do I need to change to make OBS build the package?
