zc.buildout versions
===

I have an issue with python egg versions. On my development machine I have `python-ldap` version **2.3.13**, while colleges on their machines have version **2.3.10**. Both `python-ldap` libs are installed on os level.

Is it possible to tell *buildout* not to look for newest `python-ldap` version?

I'm looking for something like this:

    # using buildout-versions extension
    [versions]
    python-ldap = any
    or
    python-ldap => 2.1

I would not like to use `buildout -N`, since I'd like to get other egg newest versions.
