[Distutils] Buildout: Version conflicts with system-wide libraries

[Gustavo Narea]

Hello,

On my Ubuntu desktop, httplib2 v0.4.0 is installed system-wide because
it's required by many things. However, I need to use v0.6.0 of that
package in my Buildout-powered project.

But when I run Buildout, I get this error:
=====
VersionConflict: (httplib2 0.4.0 (/usr/lib/pymodules/python2.5),
Requirement.parse('httplib2==0.6.0'))
=====

I've hit this problem before and what I had done is to remove the
system-wide install, which I cannot do this time.

There has to be a way for Buildout to ignore the global install, but I
could not find the answer after reading the documentation.

Can you please help me?

Cheers,
