RuntimeError: line not found on arm

[GoogleCodeExporter]

What steps will reproduce the problem?
1. install psutil on arm board
2. import psutil

What is the expected output? What do you see instead?

I expected no error instead I have:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.6/site-packages/psutil-0.3.0-py2.6-linux-armv7l.egg/psutil/__init__.py", line 52, in <module>
    import psutil._pslinux as _psplatform
  File "/usr/lib/python2.6/site-packages/psutil-0.3.0-py2.6-linux-armv7l.egg/psutil/_pslinux.py", line 55, in <module>
    NUM_CPUS = _get_num_cpus()
  File "/usr/lib/python2.6/site-packages/psutil-0.3.0-py2.6-linux-armv7l.egg/psutil/_pslinux.py", line 45, in _get_num_cpus
    raise RuntimeError("line not found")
RuntimeError: line not found

What version of psutil are you using? What Python version?

psutil 0.3.0

On what operating system? Is it 32bit or 64bit version?

arm cortex a8 

Please provide any additional information below.

the output of /proc/cpuinfo is the following:

Processor   : ARMv7 Processor rev 3 (v7l)
BogoMIPS    : 491.57
Features    : swp half thumb fastmult vfp edsp thumbee neon 
CPU implementer : 0x41
CPU architecture: 7
CPU variant : 0x1
CPU part    : 0xc08
CPU revision    : 3

so is enough to change "processor" in "Processor" in 
/usr/lib/python2.6/site-packages/psutil-0.3.0-py2.6-linux
-armv7l.egg/psutil/_pslinux.py line _get_num_cpus() can you please use:

if line.startswith('processor') or line.startswith('Processor')

thanks

Mmm... this is unfortunate because starting from now I'm no longer trusting 
/proc fs. =)
Could you please try to run the test suite and tell me if there is any failure?

This is now fixed in r1107.
As for the other failures I should put hands on an actual machine to fix them 
but I'd say they're not serious failures.
