[aur-general] Unable to submit package

[edogawaconan]

After 'cleaning up' a package I'm maintaining (nginx-unstable), and
verifying it can be built and works fine, AUR rejected the package.
Reverting to old version (with updated version) works fine.

error message:
"Missing build function in PKGBUILD."

package:
http://aur.archlinux.org/packages.php?ID=18036

Problematic version attached.
