At least, I've figured how to give the user the ability to switch
off unwanted dependencies and features.
I'm not too sure this is the right way to use setuptools...
In the attachment, the new version.
If there are no complains or hints, I'll check it out today or
tomorrow.

ERROR
=====
Looks like we're unable to fetch or install some dependencies,
or to compile the C module.
The best solution, is to resolve these dependencies (maybe you're
not connected to Internet?) or install a C compiler.
You may, however, go on without some optional pieces of IMDbPY;
try re-running this script with the corresponding optional argument:
--without-lxml exclude lxml ( speeds up 'http' )
--without-cutils don't compile the C module (speeds up 'local/sql')
--without-sqlobject exclude SQLObject ( you need at least one of )
--without-sqlalchemy exclude SQLAlchemy ( SQLObject or SQLAlchemy, if )
( you want to access a local )
( SQL database )
The following arguments exclude altogether some features of IMDbPY,
in case you don't need them (if both are specified, the cutils C module
is not compiled, either):
--without-local no access to local (mkdb generated) data.
--without-sql no access to SQL databases (implies both
--without-sqlobject and --without-sqlalchemy)
Example:
python ./setup.py --without-lxml --without-local --without-sql install
The caught exception, is re-raise below:
"""
try:
setuptools.setup(**params)
except SystemExit:
print ERR_MSG
raise
