Now I tried it and it works without problems, thanks for compiling it.
You may create a .deb, to install in the system by looking at FAM, I have version tcpdump4.0.0-1, would be good to update to the version you compiled, particularly by other application that may require it .

Another thing more, you may correct version pyrit4.0, to run in our N900, was testing with wifite_rev85 and could correct many units in this version, but I need pyrit; to work 100%. Try a ubuntu package, forcing you to install (dpkg - force) and apparently works, but there are dependencies like python (> = 2.6), libssl1.0.0 (> = 1.0.0), that make it impossible to install, and pyrit when I run, I get the same errors as reported here:

"file usr / bin / pyrit, line 4, module
import pyrit_cli
import error: no module named pyrit_cli"

This is link pyrit4.0 in ubuntu:
https://launchpad.net/ubuntu/oneiric.../0.4.0-2build1
I know they are 2 systems and architectures totally different, just wanted to see what was the problem and I think the conclusion is that, versions of python and libssl are inconsistent with pyrint4.0 in our n900.
