Comment (by jgrg):

 Yes, it doesn't look like any attempt has been made to pass CFLAGS,
 CPPFLAGS, CXXFLAGS, and LDFLAGS to `Module::Build`. I ''think'' that
 `Module::Build` wasn't widely used until the i386 > x86_64 transition was
 complete, so it may never have been used for building universal binaries.
 The default `MakeMaker` config goes through and patches each `Makefile`
 with `reinplace` to add CFLAGS and LDFLAGS.

 Binary Perl modules are usually built using the CFLAGS and LDFLAGS that
 were used to build `perl`, but it seems that MacPorts has some kind of
 cunning mechanism that keeps whatever flags are needed for universal
 builds out of the Perl config so that building a universal module doesn't
 happen by default?
