Thunderbird 2, OpenLDAP 2.3 and X11BASE migration

[Georges Discry]

I've just met a problem with those two ports.
In fact, Thunderbird includes /usr/local/include, which is the
location of two header files of OpenLDAP : lber.h and ldap.h
The problem is that Thunderbird already has those files, so during
compilation, instead of including its own files, it includes
OpenLDAP's.

I've temporary renamed the two OpenLDAP's files and so far,
compilation is going smoothly.

Note that I'm using the git X.org 7.2, so X11BASE=/usr/local

Hope it's useful,
Georges
