As it is important to control the development / runtime environment seen by
the slaves, I simply make sure the environment that is seen during slave process
creation is what I need it to be. This can be done by modifying the respective slave
buildbot.tac files. Alternatively, you could enforce a particular way to start twistd,
such as by means of a Makefile that controls all environment variables.

I have got burned a number of times when accidentally paths
(notably PATH and LD_LIBRARY_PATH) slipped in during initialization
and thus modified the way the slave would run its builder steps.

FWIW,
