this is, that the buildout will ignore the system python path ? this is
the final purpose that i want to obtain right now.

we deploy in centos servers, with python 2.5 build from source
in /usr/local (and i am trying jython 2.5 for some apps) but we prefer
virtualenv for isolate apps.

well, i think that i am going to write the recipe for:

1) build a virtualenv in the same buildout directory (with several
options, python interpreter version, --no-site-packages, etc)
2) activate the virtualenv
3) restart the buildout running with the python interpreter from the
buildout

i think that can be a good exercise for understand how to write recipes
for buildout. i found docs for recipe but very few for extensions, can u
give me some indications where i can search for this ?

thx in advance and i wait for 1.5 ^_^
