Some things seem to have changed since my last post...

Nutrak can be found here:

http://www.anpo.republika.pl/download.html#nutrak

After the download you have to uncompress the zip.
Then cd into de nutrak source folder:

cd ~/Downloads/wnutrak016/source

To compile the nutrack command line utility enter this command:

g++ -DNUTRAK_CMD -Wall nutrak.cpp -o nutrak

After that we have a utlity in this folder called 'nutrak'.

$ ./nutrak
nutrak v0.16 (C) A.P. www.anpo.republika.pl

use: nutrak [-c] [-m] [-o] [-t seconds] [-p path] gps.bin
-c - write course
-m - write miliseconds
-t - add time offset in seconds
-o - overwrite files
-p - output path
