I plan to add an option to force source or binary eggs to be used.
Something like:
egg-type = any|binary|source
where any is the default. I haven't gotten to this yet. :)
It would probably be nice to specify this at the part level.

Hi,
As some of you may know, using lxml on OSX is a big pain because of
an incompatible system version of libxml2. The solution is to ship
binary eggs, which we already do for Windows.
Now, as a first test, Stefan has uploaded this egg:
lxml-2.2.1-py2.4-macosx-10.5-i386.egg
See http://pypi.python.org/pypi/lxml/2.2.1
Now, I'm on OSX 10.5, and I've requested this exact version.
In a virtualenv, this works. It downloads the given binary egg.
In a buildout, it's preferring to download and build the egg
itself, and it calls it lxml-2.2.1-py2.4-macosx-10.3-i386.egg.
That's weird, because this machine has never had OSX 10.3 on it. :(
My Python 2.4.6 is installed via darwinports.
Now, I can probably work around this, but we're trying to ensure
that people have a sane lxml egg that will install cleanly on a
number of platforms. It's therefore pretty important that the
average user doesn't get this.
So, I'd like to try and figure out what's going on. How does
buildout decide which egg to look for? Why is easy_install in a
virtualenv behaving differently to my buildout?
Okay - I just wiped my parts/, bin/ and .installed.cfg and ran
bootstrap again. This time, it's building an egg called 10.5, but
it's still building its own from the source rather than downloading
the binary egg. :(
