Well, if you try to install .egg files built as universal binaries
on a system that uses a non-SDK build of Python on a PPC system,
you'll have a similar problem.
easy_install will look for '...-ppc', but the file is name '...-fat'.
But you do have a point: the '10.4' is actually an indicator for
the SDK version, not the version of the OS where the package
was built.

Right... the Linux major version doesn't change that often,
while the minor ones do change very often and don't really
give the user any useful information w/r to Python extensions.
As a result, using "Linux-2.6.22.19-0.4-default" in the name
would cause more user concern than necessary.

Probably. Most .eggs are Python-only, so they don't even need a
platform string. The others are mostly for Windows.

Is that binary compatibility scheme documented somewhere ?
If so, we could switch to '%s-%s' % (sys.platform, machine)
for Python 2.7.

Since this only affects easy_install/setuptools, it's probably
easier to just create a patched egg for that and then use it
with the normal Python installation. |
