Hi---
All of my figures that use MP boxes are now failing. It looks like "boxjoin"
(from the MP "boxes" macros) is not being recognized. Also, apparently
unrelated, I wonder if the comparison in "boxes.mp" is correct as it appears
that lmtx loads "mp-xbox.mpiv" instead of "mp-xbox.mpxl". Here is some log
output and a (mostly) MWE.
Thanks for any suggestions,
