Thanks you, Ben!
I got the source xorp.ct. Run scons and encounter the error message:
TypeError: expected a character buffer object:
  File "/usr/src/xorp.ct/SConstruct", line 485:
    Split(env['CFLAGS']))
  File "/usr/src/xorp.ct/SConstruct", line 484:
    lambda s: not s.startswith(tuple(strip_pg_flags)),

Anything missing?
