hi, 
I run the allmydata-tahoe-1.9.1-SUMO in ubuntu11.0 without internet connected,and there is a problem like this:

******************************
why does tahoe-SUMO still download packages as tahoe-deps packages already in place? Does the -SUMO has everything it need? or It has to connect the internet?

This means that it attempted to compile Twisted from source, and it  
failed to compile. This part of Tahoe-LAFS packaging is confusing,  
because there are two different ways that it attempts to satisfy the  
requirement for Twisted. First, it checks whether it can download a  
precompiled binary of Twisted for your platform. It looks in at least  
these three locations:  

https://pypi.python.org/pypi/Twisted  
http://twistedmatrix.com/trac/  
https://tahoe-lafs.org/source/tahoe-lafs/deps/tahoe-lafs-dep-eggs/README.html  

That last location is under our control, and we could fix this problem  
for you if someone would build a Twisted binary for your platform that  
we could host there. Would you please post the output of:  

python -c 'import platform;print platform.system();print  
platform.architecture();print platform.python_version()'  

Anyway, if the build system doesn't find a precompiled binary of  
Twisted for your platform then it tries the other approach, which is  
that it downloads the source code of Twisted and tries to compile it.  
The reason it failed to compile is that you don't have the "Python.h"  
file installed. That file comes from the "python-dev" package on  
Ubuntu, so if you install that package then I believe your build  
process will proceed.  

Regards,  

Zooko
