i experienced problem with call'ing python unmarshalled
and eval'ed code. 

similar problem described in mailing list, but
unfortunately has not got any solution or work-around. 
http://mail.python.org/pipermail/c++-sig/2003-October/006094.html

actually I have code like this: 
-------------
import m

class A:
  def do(self): 
    print m.User().GetName()
------------
test.py
a = A() 
a.do()

running script from python works perfectly. but when I
call 'do' from c++ code I get following error : 
PyObject_CallMethod: exceptions.NameError:global name
'm' is not defined

I checked locals dictionary, it contains missing name
('m').

Can you provide the c++ code?  Thanks.

How do you call "do" from your C++ code?

"m" isn't a local variable, so what you stuff into the
locals directory doesn't matter; the important thing is that
the module associated with the function
(A.do.im_func.func_globals) contains the right thing.

Closing on lack of input from OP.
