> Yes, so, you have raised this in a timely fashion.  While I was backporting a patch against orcus for the 6-0 branch last night, I did notice the possibility of this very issue, and was thinking of how to address it for that branch.  Since you've already discovered this and emailed it to the list, let me provide my thoughts on this.

I think that should be done. I uploaded 0.13.3 to Debian (and Ubuntu
synced it) for 6.1 needing it (and bumped the build and runtime
dependency there already..) but when 6.0 breaks with it (should have
known better and tried...) that imho should be done, yes...

Will backport both patches above as a local patch for now.
