Import fails on FreeBSD 7.2

What steps will reproduce the problem?  
1. install via python setup.py install
2. import psutil 3. 

What is the expected output?  


What do you see instead?  
Python 2.5.4 ( r254 :67916, Apr 14 2009, 08:39:49) 
[GCC 4.2.1 20070719  [FreeBSD]] on freebsd7
Type "help", "copyright", "credits" or "license" for more information.
>>> import psutil

    TOTAL_PHYMEM = _psutil_bsd.get_total_phymem()
SystemError: error return without exception set What version of psutil are you using? On what operating system? trunk.  fails on 0.1.2 also 

Please provide any additional information below.  
I subbed in a function to replace the failing one using a call to sysctl.
Diff is attached.  Not a permanent solution though because it's slow.

This is strange as there are no problems on both FreeBSD 7.0 and 7.1.
Didn't have the chance to install 7.2 to try this out.
Are we talking about 32 bit architecture?

Marking the issue as high priority as it makes impossible to use psutil on FreeBSD.

I think HW_PHYSMEM may have changed in FreeBSD 7.2 and it's causing the call to
sysctl() to fail. We will need a FreeBSD 7.2 machine to test on and confirm but my
guess is that FreeBSD 7.2 changed the HW_PHYSMEM to a long instead of an int.

Downloading 7.2 now, I'll try and setup a FreeBSD 7.2 env and sort this out over the
next few days.

good news: I have FreeBSD 7.2 installed and running
bad news: I can't reproduce this issue

[jloden@freebsd7-2 psutil]$ python
Python 2.5.4 ( r254 :67916, Dec 15 2009, 21:07:06) 
[GCC 4.2.1 20070719  [FreeBSD]] on freebsd7

>>> import psutil
>>> 

Two possible guesses

1) the system this was reported against is 64bit instead of 32bit
2) I don't have enough RAM for my system to cause the int value to overflow

If the original reporter or anyone else that can reproduce this issue can let us know
if the system was 64bit and how much RAM was on the system that would be very helpful.

I finally managed to install a 64 bit version of freebsd.
It seems there's a lot of work to do for 64 bits systems. r439 fixes this specific issue and allows psutil to be imoprted, but 8 test failures
reveals that there are other issues which require the code to be more careful when
types are declared.

Verified that psutil.TOTAL_PHYMEM matches what shown by "sysctl -a | grep hw.physmem".

Summary: FreeBSD 64bit support

Here is a summary of functions which need to be fixed/converted for 64 bit systems:

get_avail_phymem()
get_pid_list()
uid
gid

As of right now test suite reports 10 failures.

Since we already have Issue #61 for 64bit support I am changing this issue back to
just the import failure that was originally reported. Also committed r457 to solve
this without needing conditional macros. We can just use a long since that does not
cause a problem on 32bit FreeBSD.
