Error message upgrading xlockmore

[J. Altman]

Hello...

Upgrading xlockmore via portmaster, the following occurs over the
last three or four days:

========================================

I'm assuming a bug report should be opened; but X11 or just the general ports bugs list?

In case it's relevant:

FreeBSD chthonixia.chthonixia.net 12.0-RELEASE-p10 FreeBSD 12.0-RELEASE-p10 r351322 CHTHONIXIA  amd64

And everything else builds or rebuilds fine.

Thanks,

Joe
