7 months ago I worked around it by deleting line 69 (nice) in https://github.com/davidgiven/ack/blob/db5a32c68c4a60ca26a3927a799ea662b5b2b0e5/lang/m2/comp/build.lua#L69.
The whole build step seems to have been left over when in 04f723b4 the system of keeping markers in C files that are then fixed with sed in build, seems to have been ripped out of the modula part. The file arguments to the build step have been removed. That's why sed hangs, without file arguments it waits for stdin input.
Removing the line seems to have no adverse effects, it builds and tests fine. I don't have the time right now to get confident enough to prepare a PR with the fix, so I'll just document it here for David.
Without changing anything in the makefile, in a fresh repository downloaded today, on a Mac OS X running 10.15.7 make hangs when it gets to:
lang/m2/comp+next_c.
I did a make clean and tried again with same result.
here are the preceding n output:
