That's not exactly what `guide.macports.org` states - for `universal_archs`, it doesn't discuss `configure.universal_archs`. IMHO it's a bit unexpected that there are 2 settings to control what architectures a port supports!

$universal_archs contains exactly what is set in macports.conf (so does 
$build_arch). ${configure.universal_archs} is the archs that will 
actually be built with +universal, and may differ from the macports.conf 
value due to the supported_archs of the Portfile and of the chosen SDK. 
(That is also the case for ${configure.build_arch}.)
