From what I read, pbi is some PC-BSD build thing, correct? Did you get
into touch with the relevant PC-BSD people on that matter already? If
not, I think, it would make sense, if we involve them in this discussion
later on, since it might be that either

- pbi contains a bug of not using a clean environment or port build
  instructions or
- FreeBSD's python port make system has a glitch to ignore libxcb's setting

I'm CC'ing python@ here on that matter. From what I can see in
bsd.python.mk is that the following might happen:

.if !defined(USE_PYTHON)            # set by graphics/blender
.if defined(USE_PYTHON_BUILD)       # usually set by x11/libxcb, but ignored
                                      since blender sets USE_PYTHON
...
...

python@: Can you confirm that this could occur (see below for the
complete issue)?

Best regards
Marcus
