Josh,
For dev versions if we have a really strict blocker requirement I
think it's okay as a temporary measure. I do not think we should peg
to versions otherwise in dev because we should move along with these
packages when there are bug fixes or other good reasons to do so. It
also gets us a head start in discovering incompatibilities etc. in
later versions. When there is a problem, we can make a judgement call
about whether to change our code or wait to update to theirs. In this
case, I'd actually like to see a bit more info: http://trac.openplans.org/melkjug/ticket/336#comment

For deployable production / versions in testing we use an installer
that maintains a fixed copy of the exact dependency we want to deploy
with.
These are conservative versions that have been proven in development
practice and are known to work.
The curdle package is used to build these installers ( https://svn.openplans.org/melk/curdle/trunk/
)
To update a dependancy for production, you can alter (for example)
https://svn.openplans.org/melk/curdle/trunk/deps/
update the ref in:
https://svn.openplans.org/melk/curdle/trunk/Makefile
Note these deps must satisfy what is listed in the setup.py's of
various packages or the installer will fail.

In getting a working dev instance running at dev.melkjug.org, I've
recently had to peg melkjug trunk to specific versions of various
dependencies in its setup.py to prevent incompatible newer versions
from being installed:

http://trac.openplans.org/melkjug/changeset/1941
http://trac.openplans.org/melkjug/changeset/1948
I remember hearing about some ups and downs to putting this in
setup.py... What are best practices re dependency management? Should
I be going about this some other way?
There could very well be additional newer packages that are getting
installed that have introduced breakages I haven't run across yet.
Should I go ahead and peg trunk to all the specific package versions
I have in my working local instance (installed I can't remember how
long ago)?
