I think I can fix this in modulegraph, I'm not quite sure why it works in 2.6
but not in 2.7 though. Are you using the same version of crcmod in both cases?
My current impresssion of what's going on here: crcmod.__init__ contains:
try:
from crcmod.crcmod import *
import crcmod.predefined
except ImportError:
# Make this backward compatible
from crcmod import *
import predefined
A test with a simular package structure fails on both 2.6 and 2.7, but works
with 3.2. Modulegraph fails because it creates a MissingModule node for
crcmod.predefined, which seems to indicate a bug in how we process imports in a
package as it should have created a MissingModule node for
crcmod.crcmod.predefined for the second import statement and then a real node
for the last one.
