Issue building MM 1.14 on Ubuntu 18.04

[Nick]

Hey,

Just having an issue building MM 1.14.0 on Ubuntu 18.04.x (fully updated). I have a relatively recent version of /usr/share/aclocal/ax_is_release.m4 on my system, and have tried replacing the contents of that file with the most recent version of it found on the GNU website also.  The weird part is that I am not building from a git repository, I am using the stable release archive, so I am not sure why it is trying ot use this in the first place.

Does anyone have any tips or advice to help me troubleshoot further?  By the way, it builds fine on Ubuntu 20.04.


Here is a relevant snippet from the build output:
