If zope.schema is the only one that is complained about, then using 
3.6.0 seems safe enough:
http://pypi.python.org/pypi/zope.schema#id7
Just add zope.schema = 3.6.0 in your [versions] section.

Alternatively, see if pinning z3c.form to 2.3.4 helps.

Handpicking the correct versions for z3c.form and plone(.app).z3cform 
for the Plone version you are using can be tricky...

Note that you are pulling in Products.CMFPlone 4.1a1 here.  To avoid 
that, try pinning Products.CMFPlone = 4.0b1, like Plone 4.0.3 does:
http://dist.plone.org/release/4.0.3/
Or use Plone 4.0.3 yourself; it is not releases officially yet, but that 
is only pending the arrival of Windows builds.
