I've tried installing the dependencies one at a time in various orders, but I always get the same error message. This is on a fresh MacBook Pro M1 (ARM64) with no existing macports installation. I'm installing into a custom directory (/opt/digikam.arm64).

Try "port install vala -valadoc", before the install libproxy.
