M1 chip, this error message seems backwards; no arm64 version of valgrind-macos-devel?

The message is correct, not backwards. It tells you valgrind-macos-devel is available for x86_64 but not for arm64. 

To use this on your arm64 Mac, MacPorts will need to install all of valgrind-macos-devel's dependencies with the universal variant.

MacPorts is claiming it cannot do this because the dependency libtool doesn't have a universal variant. 

I can't understand that. There's nothing in the libtool port that should prevent it from having the default universal variant. IIRC we previously had such a problem where the portindexes on the server were missing the universal variant. However I just checked them and all of them show a universal variant for libtool. 

Make sure your port definitions and MacPorts are up to date:

sudo port selfupdate
sudo port install valgrind-macos-devel

If no change, try installing libtool with the universal variant explicitly:

sudo port clean libtool
sudo port install libtool +universal

If that works, it wouldn't explain why MacPorts thought the variant was missing but might at least allow you to install the port you want to use.
