This list is for asking questions, so there's nothing wrong with you
asking questions :-).
The instructions below are a good starting point, but I suspect you
might not have something installed correctly (or at least not in a way
we've tried before). The code that's failing is this:
extra_python_paths = [
Dir('src/python').srcnode().abspath, # M5 includes
Dir('ext/ply').srcnode().abspath, # ply is used by several files
]
sys.path[1:1] = extra_python_paths
from m5.util import compareVersions, readCommand
What that's supposed to be doing is adding src/python and ext/ply in
the M5 source tree to your python path. Then it imports m5.util which
it should find in src/python. The src/python/m5 directory and the
src/python/m5/util directory both have __init__.py files in them which
makes them act like python packages and is why you should be able to
import from them.
When you run scons, it reads in that SConstruct file which is run as a
python script more or less. Very early in that file the code above is
executed, and that's not working for some reason. I would expect the
problem to be in how scons or python are installed (or their
versions), the way they're being started on the command line, or
something about the actual files or paths of the M5 source tree.
You could try printing out the sys.path list to see if anything looks
wrong. For me the first few entries in that list are the following:
['/home/gblack/m5/repos/public',
'/home/gblack/m5/repos/public/src/python',
'/home/gblack/m5/repos/public/ext/ply',
You can see where src/python and ext/ply have been added in.
Even though I think the problem might be from the way your system is
set up, it would still be a good idea to follow Victor's instructions
and see if that works for you.

hg clone http://repo.m5sim.org/m5
cd m5
scons build/ALPHA_SE/m5.opt
That should be enough to get you started.

I am a newbie to m5 simulator and I really do not know where to look for
answer, sorry about ask the question here.
I tried to install M5 on my ubuntu10.10. And I followed the instructions
given in the following website
http://www.m5sim.org/wiki/index.php/Compiling_M5 [3]
but it always gives such error message
scons: Reading SConscript files ...
ImportError: No module named m5.util:
File "/home/victorlxy/src/m5-stable/SConstruct", line 121:
from m5.util import compareVersions, readCommand
And I am so frustrated because I do not know where the
problem is from,
such as scons or m5 itself, since I dowloaded scons from www.scons.org [4]
and installed it.
Any help will be greatly appreciated
Best Regards
Victor
