I deleted my old tree (downloaded yesterday) and reget the source:

 cvs -z3 -d:pserver:anonymous at cvs.boost.sourceforge.net:/cvsroot/boost
co boost

and then in boost-root:
 cvs update -dRP -rmpl-development boost/mpl

This time it works. And m1.so m2.so etc are also ok.

Howerver, I have enum and operators (op_add, op_sub etc) in the library
which are handled correctly in boost.python v1. What is the right way in
v2 for them?

Thanks again.
