Hey Darryl. Our minds were in a similar place today. I finally had
decided to move away from my system python starting on my mac and also
having a spot of trouble. I put something simple together below to
illustrate what happened in my instance.
Here the eggs built with the python would not install. I initially
though it was the lxml I was compiling, but it was just happened to be
the first part requiring the custom-python. Eggs were made, and I could
see the temp folder also, but when was finalizing the install, it threw
the error and without much verbosity, the tempfolder it was installing
into disappeared.
Note, I did not include the custom-python as a part in the buildout. I
tend to like the python24:location type of notation since it is fairly
explicit when you have a number of pieces of software you are building.
Regards
David

Some verification it is using the right python...

We have the best distribution that satisfies 'setuptools'.

Because this distribution was installed --multi-version, before you can
import modules from this package in an application, you will need to
'import pkg_resources' and then use a 'require()' call similar to one of
these examples, in order to select the desired version:
pkg_resources.require("Cheetah") # latest installed version
pkg_resources.require("Cheetah==1.0") # this exact version
pkg_resources.require("Cheetah>=1.0") # this version or higher
Note also that the installation directory must be on sys.path at runtime for
this to work. (e.g. by being the application's script directory, by
being on
PYTHONPATH, or by being added to sys.path by your code.)
While:
Installing interpreter.
Getting distribution for 'Cheetah==1.0'.

I'm trying to created an isolated environment using buildout. I had
understood that defining a custom build python would ensure that all
eggs are installed and compiled with the custom python.
But when the buildout comes to install ZODB it is being compiled agains
the system python headers. (-I/usr/include/python2.4). Which is not what
I want, and at that point the custom python has not even been built.
Any thoughts.
[buildout]
python = custom-python
parts = python

[custom-python]
executable = ${buildout:parts-directory}/python/bin/python
Your buildout doesn't mention ZODB3 or anything that uses it, so it is
hard to comment.
