Thanks for the report. You are the first person to file a problem report
about this conda package, but perhaps not the first person to encounter the
error. I don't have an M3 machine myself. One other person has reported
success in installing the package. (If anyone else on the list has access
to an M3 machine, please consider trying to install the conda package and
reporting the results. Instructions are at the "Download Amber" tab on the
Amber web site.)
Could you provide the output from "conda search arpack"? And, is your conda
newly installed from miniforge, or an older version, or one that came from
something homebrew or macports? If the latter, it is possible that a "conda
update" might help.

Try adding this to your run_cmake file:
-DDISABLE_TOOLS="moft;packmol_memgen"
It would also be helpful to know the output of "clang --version".
As I think I may have mentioned before, there seem to be about as many
different reports of what happens on M3 as there are people making such
reports. Maybe we can all get to the bottom of this problem soon.
...thanks again....dac
