Almost happy ubuntu 12.04.1 user here.
I installed python and virtualenv with
sudo apt-get install python-dev python-virtualenv
and am using the commands
$ PIP_CACHE=$HOME/pip_cache
$ virtualenv --no-site-packages sandbox
$ cd sandbox
$ . bin/activate
$ pip install --no-install --use-mirrors -I --download=$PIP_CACHE
-emaster
to install buildbot from source while saving downloaded packages.
Then, on an isolated host, after copying ~/pip_cache, I run
$ PIP_CACHE=$HOME/pip_cache
$ virtualenv --no-site-packages sandbox
$ cd sandbox
$ . bin/activate
$ pip install --find-links=file://$PIP_CACHE --no-index
--index-url=file:///dev/null -emaster
in an attempt to get rid of the need for an internet connection.
( As recommended in the second answer in
http://stackoverflow.com/questions/4806448/how-do-i-install-from-a-local-cache-with-pip
and alluded to in http://carljm.github.com/tamingdeps
and http://www.pip-installer.org/en/latest/usage.html#install-packages )
This does fill the cache directory with some tarballs:
$ ls $PIP_CACHE
buildbot-0.8.8-pre-121-g0ea11a4.zip distribute-0.6.28.tar.gz
python-dateutil-1.5.tar.gz sqlalchemy-migrate-0.7.2.tar.gz
Twisted-12.2.0.tar.bz2
decorator-3.3.3.tar.gz Jinja2-2.6.tar.gz
SQLAlchemy-0.7.8.tar.gz Tempita-0.5.1.tar.gz
zope.interface-4.0.1.tar.gz
but sadly, installing on the isolated system fails with

I see from
https://groups.google.com/forum/?fromgroups=#!topic/python-virtualenv/K05_oEBiRPw
http://lists.debian.org/debian-release/2010/08/msg01621.html
and
http://packages.ubuntu.com/precise/all/python-virtualenv/filelist
that the directory /usr/share/python-virtualenv is where setuptools
comes from. Should there be a setuptools_trial egg there, too?
Or should setuptools_trial somehow be in my $PIP_CACHE?
I'll gladly take a workaround like "just pre-install setuptools_trial like
this".
(This is made harder to debug by my visceral hatred of complex systems that
make it hard to achieve repeatable builds, and of rabbithole ecosystems in
general. I'm trying to keep an open mind, but it's hard when you're a
curmudgeon.)
Thanks,
Dan
