I've ha problem installing pyrit:

CPU: intel i5-2500k
GPU: ATI 6950 2GB

I'm not on a Virtual Machine

instructions:
apt-get purge pyrit
svn checkout http://pyrit.googlecode.com/svn/trunk/ pyrit_svn
cd pyrit_svn/pyrit
./setup.py build
./setup.py install --record ~/pyrit.txt
cd ../cpyrit_calpp
./setup.py build
./setup.py install --record ~/pyritcalpp.txt


I do:

command: apt-get purge pyrit

root@bt:~# apt-get purge pyrit
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Couldn't find package pyrit
root@bt:~#

i go on anyway
Command:svn checkout http://pyrit.googlecode.com/svn/trunk/ pyrit_svn
result OK

command: cd pyrit_svn/pyrit
./setup.py build

I think there is a problem with the compiler....

I followed all the previous instruction and all gone fine
which is my mistake?
