[erlang-questions] Problem with debugger:start()

MacPorts defaults to 64-bit when the machine can support it. Unfortunately, it does not seem possible to install a 32-bit VM in a 64-bit MacPorts install. Instead, you have to clear out your entire MacPorts install, and set the 32-bit architecture as the default before you install packages.

I am trying to figure out a way around this issue. That does not require port removal. It might be enough to just adjust the build settings in the Portfile.

If that works, I'll add a variant case and commit it.
