The source tree is configured thus:

./configure -developer-build -opensource -no-glib -nomake tests

and it builds without errors (if I use -no-glib, otherwise it fails).

When I do this:

sudo gmake install

I get these errors (followed by a number of similar errors):

Undefined symbols for architecture x86_64:
