My guess as to what happened: I was using python2.7 (which is EPD,
containing a tonne of packages including an older version of xlrd).
BTW, I have no idea what EPD means.
Enthought Python Distribution, I should emphasise *was* using above...
Since that xlrd was getting picked instead of the one in the develop line
(wasn't that bug supposed to be fixed in buildout 2?!)
There was quite a bit of discussion about this recently and there
was no consensus that develop eggs should be preferred to
over non-develop eggs with higher versions.
The non-develop eggs here have significantly *lower* version numbers.
(and really, if I say I'm developing a package, why would a
non-development version be picked?!)
At times like this (when I've just wasted 1.5hrs chasing my tail) I really
truly hate buildout :-(
It's times like this that I really really hate it when people insist on using
dirty Pythons when they should know better.
Two comments, the first an order of magnitude more important than the
second:
1. I *was using a clean python*. Buildout decided to use some crap *it*
left lying around from a totally different Python installation when I
ran python2.6<clean, build form source> bootstrap.py
2. There is some practicality here. EPD provides suitable versions of a
tonne of packages I can't and often don't even want to try compiling
from source. Unfortunately, it provides some packages of which I want
newer versions. I know this is a hard problem, one that Gary Poster
tried to solve, and I appreciate that implementation didn't turn out well...
cheers,
Chris
