Subject: mac build: make a couple of build dependency hints soft imports
X-Git-Url: https://git.rkrishnan.org/?a=commitdiff_plain;h=3603608e6894afa3426699799c88cbd92cb59075;p=tahoe-lafs%2Ftahoe-lafs.git

mac build: make a couple of build dependency hints soft imports

the existing environment on otto requires a few build hints in order for
xml parsing to work properly.  these hints are unnecessary, and moreover
their import by depends.py is broken, in the 10.5 environment in which
zandr's buildslave is running.
