Don't install dependencies when using pip to download python packages

[dknecht]

This will work now:

fpm -t deb --deb-user root --deb-group root -s python --debug --python-pip /usr/bin/pip --iteration 1 -v 1.0.0 elasticsearch

Thank you much! :)

After this patch, it fails for me:

Successfully downloaded elasticsearch {:level=>:info, :file=>"cabin/mixins/pipe.rb", :line=>"46"}
Could not find 'setup.py' {:path=>"/tmp/package-python-build20140710-23548-std9fv/elasticsearch/elasticsearch/setup.py", :level=>:error, :file=>"/home/jls/projects/fpm/lib/fpm/package/python.rb", :line=>"92"}

I tried with elasticsearch and django. Same results.

Seems like pip installs to another directory deeper? or something?

In the build directory I see django/django/django which is a bit odd ;)

Oh, I see. --no-install doesn't actually work anymore in pip.

I'll file a separate bug about this.
