C:\\Python25\\lib\\. contain *many* packages with .dll files - i can't
just zip it.
wxPython,pyOpenGL,PIL,tk and so on. On Fedora 6 more than 40% dirs of
/usr/lib/site-packages contained .so files. Some of them add dirs to path
(wx,PIL,Gtk,...).

yum,apt and other will bee very angry if i zip site-packages directory.
I don't known any package manager which can properly work with
packages installed in archive.

Are setuptools can  work properly with packages packed in one big zip archive
(i really don't known)?

And finally - if it's so easy why this don't done already? Python widely used
in many linux distros and i don't known any one which can install even
standard library
in zip archive. Most of users can't done it(because they don't known
about python at all).
Or this just because lack of time?

Yesterday i test some programs with strace and receive follow results:
command               num of sys_calls  num of FILE_NOT_FOUND
python -c "pass"                     2807              619          ~20%
yum                                       20263          11282        >50%
pychecker                               6181            2527         ~40%
meld(nice GUI merge util)        16075            8024          50%
ipython < exit.txt                    16448            8957         >50%
(exit txt contain "exit()\n")
(if filter some of  FILE_NOT_FOUND
which are not produced by python modules search)

BTW. In trace results many call chain like this:

open("/usr/lib/python2.4/site-packages/Durus-3.6-py2.4-linux-i686.egg",
O_RDONLY|O_LARGEFILE) = 6
......
_llseek(6, 98304, [98304], SEEK_SET)    = 0
read(6, "\340\377\224\322\373C\200\177.\245\367\205\0\307x\207\r"...,
4096) = 4096
_llseek(6, 102400, [102400], SEEK_SET)  = 0
_llseek(6, 102400, [102400], SEEK_SET)  = 0
_llseek(6, 102400, [102400], SEEK_SET)  = 0
.....
and so on. As i understand all
_llseek(6, 102400, [102400], SEEK_SET)  = 0
calls after first are just heating air.
