Summary: Fails to build under non-root

Initial Comment:
setup.py build should not require root, however it
attempts to write to /usr/share/pyx:

+ python setup.py build
running build
running build_py
running install_data
creating /usr/share/pyx
error: could not create '/usr/share/pyx': Permission denied
error: Bad exit status from /var/tmp/rpm-tmp.18551 (%build)

Attached patch changes way when siteconfig.py is written.

I see. I think, this is partially due to the fact, that its not totally trivial to 
create a siteconfig.py on the fly. You need to do something like what we 
already have. (In that sense its fine ... we already have it.)

OTOH I would not like to hard-code the position of the config file. Take 
fink where global config files are located at /sw/etc there. And what's /
etc on Windows? (Beside the problem, that "/" is not available and 
distutils fails although its not documented, but I'll work around that for 
the future.)

I think it would be best to also write some adjusted version of 
siteconfig.py in the build-directory. I'll just code that and then we'll see 
whether it fits everybodies needs ... (or at least almost everybodies)

Well I prefer not to have such "configuration" files, so I
try to write some kind of autodetection (and hardcode config
file in /etc). You can find this in my application Wammu and
I saw simmilar thing in imgSeek.

Ok. My idea was to already create the final version of siteconfig.py in the 
build directory. But you're right that this is too much burden to cover for 
a build command. build_py should better not depend on install_data.

Anyway I like your suggestion in modifying install_lib instead of build_py 
and replace siteconfig.py right after the copy_tree performed by 
install_lib's install method. But why not keep the dependance on a 
modified version of install_data? I think its better to keep the path 
calculation for siteconfig.py in install_data. Any objections?

BTW there is another problem with this new version (your and mine as 
well): PyX does not run from the build directory anymore, since there is 
no build_data to copy the data into the build directory and the 
siteconfig.py from PyX referes to some relative paths. Should we fix 
that? I'm not sure whether its needed to have a running version in the 
build directory, but that's something I do not yet like too much. We could 
*additionally* fix the siteconfig.py by our own build_py command but 
keep it to be relative paths. Or implement a build_data ... ?!
