Pascal,

I looked at the module sets again. perl-xml-simple and perl-xml-parser were there because gtk-doc used to 
require them. It doesn't any more (it was rewritten in python), so I took them out of bootstrap.modules and 
forgot to take them out of jhbuildrc. That means that expat doesn't need  a universal build anymore. I've 
pushed a fixed jhbuildrc-gtk-osx to pipenv.

That aside you may have some problems at runtime with the 10.14 SDK and MAC_OS_X_VERSION_MIN_REQUIRED=101300. 
It depends on whether Apple has updated any of the non-framework libraries that we use between the two 
versions. Unfortunately the stub linking introduced in 10.9 doesn't completely mask all of the symbol changes 
between library versions.
