First PKGBUILD, please review

I've just created my first PKGBUILD, would you mind reviewing it before I post it to AUR?

Works like a charm! Thank you!
Some formal, very minor issues:
* Arrays like (i686 x86_64) should be written ('i686' 'x86_64'). Also valid for the depends.
* Delete empty fields (groups, makedepends, install)
* replace mkdir -p by install -d
Also formal, but less minor and not your fault: There is no clear license statement made by the author. "BSD" is not a license, but an idea of a license, or a bunch of similar licenses. I would put an echo line with some sentence at the end of the PKGBUILD, redirected to $startdir/pkg/usr/share/licenses/$pkgname/BSD.
