# Contributor: Nathan Owe. ndowens04 at gmail dot com
pkgname=mirdir
pkgver=2.1
pkgrel=1
pkgdesc="allows to synchronize two directory trees in a fast way."
arch=(i686)
url="http://mirdir.sf.net"
license=('GPL')
depends=()
makedepends=('make' 'fakeroot')
source=(http://downloads.sourceforge.net/sourceforge/mirdir/$pkgname-$pkgver-Unix.tar.gz)
md5sums=('56afe2aae7983176fd804c264740d6a2')

build() {
  cd "$srcdir/$pkgname-$pkgver-UNIX"

  ./configure --prefix=/usr
  make || return 1
  make DESTDIR="$pkgdir/" install
}

when i try to do makepkg -s it gives
