This PKGBUILD need some cleaning: libxfcegui4 is deprecated. You only need xfce4-panel-git in depends() line.

And install file is now useless...

@drhill1 : Thanks! PKGBUILD updated.

Just installed this and it works great, but the pkgver() line within PKGBUILD provides a version that keeps wanting to be updated. I changed the line to the same as that in exo-git and all works well.
