Comment:

 I'm happy to change osxvnc so that universal is not the default. I just
 didn't know exactly how to do it.

 "`xcode.build.settings ARCHS=$(NATIVE_ARCH)`" is not the solution; the
 port self-destructs with the message "`can't read "(NATIVE_ARCH)": no such
 variable`".

 "`xcode.build.settings ARCHS=\$(NATIVE_ARCH)`" isn't it either; this
 passes $(NATIVE_ARCH) on to the xcodebuild line, but that then complains
 with "`sh: line 1: NATIVE_ARCH: command not found`"

 "`xcode.build.settings ARCHS=\\\$\\(NATIVE_ARCH\\)`" gets past the errors
 and the build completes, but still ends up being universal.

 I'm not keen on calling out to `uname -m`...

 I'll do it the way Anthony Ramine has been doing in his ports for some
 time. Committed in r35717. Thanks for all the suggestions though!

 No revision bump is necessary. Users who had the port installed previously
 automatically had the +universal variant selected. Users who now install
 the port will get it without +universal, but can select +universal if they
 want it.
