Yeah, it seems that it is in binary form already, so I have downloaded the Slackware version in tar.gz format instead of .rpm package of RedHat.
Now I have doubts - I have extracted the archive's contents and there is xplns executable and also an install.sh script. Should I run the install.sh script? If so, why? After all, there is executable file, things are compiled, so in WIN I would just click the executable to run the program. I don't want to do try and error without consulting you first, because I don't want to break something in my system.
