"use_configure no" turns off the universal variant. (The default universal variant functions by modifying the environment variables and flags sent to a standard autoconf configure script; that can't work when you use "use_configure no" to tell MacPorts that this project does not use a standard autoconf configure script.)

Also, even if the default universal variant appears to be there, [get_canonical_archflags] does not recognize it and you still have to put "variant universal {}" above it. Good to know that "universal_variant yes" also works; that may be the preferable way to write it.
