I have a few questions and comments about the Mac binary of matplotlib
A few things struck me as scary:
- There are no instructions; when you unzip it you get just an egg and
that's it. I was able to find the magic incantation on the web, and
fortunately I already have easy_install installed. But it would be a big
help to have a ReadMe that tells how to install easy_install and how to
use it to install the egg.
- The zipped egg includes dateutil and pytz. But I already have those
installed (both due to using older matplotlib and because I use dateutil
in my own code), so now I have two sets in different locations. This is
worrisome. Which one will get used? Does it matter if I import dateutil
first or matplotlib first? (I deleted the versions in the matplotlib egg
to remove doubt.)
I thought easy_install could handle dependencies (and indeed, per the
next item, it seemed to be trying to do so). If so, couldn't it only
install them if not already present?
- When I ran easy_install it started searching the web and installing
stuff. But what was it downloading and installing? The messages were
very vague. I already had dateutil and pytz, so did the egg, so it would
be crazy for it to download those. But what in the world else could it
possibly need? Surely the freetype and png are already statically linked
in (or perhaps it's using Apple's freetype). Surely it doesn't want to
download those as libraries and install them? Surely it would not
install wxpython, since that is optional?
I do appreciate the effort that goes into producing these binaries. (I
used to make a matplotlib package installer for pythonmac.org and was
glad to give it up.) And the results do seem to work.
