Plus there would be maddening dependencies - "oh, in order
to use this I need dl that". "oh, that package is missing", "why
that doesn't work?" - and time gets wasted.
On Linux, quite a lot of code had to be written to resolve
dependencies like "a.rpm depends on b.rpm depends on
c.rpm ...". Sure, apt is a wonderful tool for resolving
such stuff - but I've seen even apt choking sometimes on
dependencies it couldn't resolve, esp. when the package you
attempt to dl is broken in some way. Reason - apt-get says
"sorry, what this package depends on is broken and I can't
find anything else in your /etc/apt/sources.list that would
be appropriate". Result? Nobody gets to use Pine on this
machine, unless I compile it myself (which I finally did).
Sure it _can_ be done, but essentially it's a waste of
time that this person could devote to doing smth else.
It doesn't happen often, but it happens. Why get into
resolving such complexity if you don't have to?
There are good reasons to use tools like apt-get or yum or
up2date on Linux: you can't fit the bugfixes on a CD that
come every day, obviously, there's too much of it all to
fit simply everything anybody could ever need on the media,
etc, etc. However, with Python that's not a problem, because
distro is smaller and it doesn't change _that_ often, as lots
of packages on Linux are updated almost daily.
One of the options for Python could be to have two distributions:
one standard, basic distribution, and the "Stuffed Python" based
on the standard, created simply by piling all the good stuff on top of
It's a man's life in a Python Programming Association.
