 My cairo @1.14.2_1+quartz is built without x11 support, and I added
 py34-cairo @1.10.0_3 just now. However, when I then try to load cairo from
 Python, loading the library fails with what I suspect is a missing x11
 symbol:

 {{{
 >>> import cairo
 Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File
 "/opt/local/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4
 /site-packages/cairo/__init__.py", line 18, in <module>
     from ._cairo import *
 ImportError:
 dlopen(/opt/local/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4
 /site-packages/cairo/_cairo.so, 2): Symbol not found:
 _cairo_xlib_surface_get_depth
   Referenced from:
 /opt/local/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4

Comment:

 Did you get a binary from our packages server, or build py34-cairo from
 source? I suspect you got a binary. I suspect py-cairo builds itself
 differently depending on whether cairo has x11 support or not. Therefore,
 py-cairo should have an x11 variant, and use the require_active_variants
 procedure in the active_variants 1.1 portgroup to ensure a match between
 the variants of the py-cairo subports and the cairo port. That is what was
 done in r100265 to fix #34889. It was undone in r129111; see #38606. The
 removal of this code appears to have been incorrect and it or something
 like it should be reinstated.
