[MAINTAINER UPDATE] x11/lumina port currently won't build - fix included

[Bryan C. Everly]

Hello ports@,

Looks like we missed a comma in the makefile which is preventing the
current Lumina 1.4 port from building.  I've attached a diff which I
painfully built every dependency from source on my Thinkpad X230 to
verify it was working correctly.

Thanks to Martijn (copied) for notifying me.

I'd appreciate a set of eyes on this and for someone to please commit
it on my behalf.

Thanks,
Bryan
