I submitted an orphan request because a previous commenter on AUR ran into the same problem as I did. I assumed the package was unmaintained because he reported the problem a month ago and received no reply.
Anyway, you'd only need to bump the pkgrel and sync the .SRCINFO with the PKGBUILD, i.e. `makepkg --printsrcinfo > .SRCINFO`.

Kind regards,

The package builds fine.. no idea where your problem is. Next time do
a comment and not submit an orphan request without informing the
maintainer first:
