This guide was tested on clean installation of OpenBSD 5.7.
Everything is done from command line, that means everything can be done over ssh on remote server.
In my case was only base system installed, that means after startup and login i was already in command line and working directory was my home directory.
For database support you need database development files for database that will be used.
If you are not in command line then you need to go here some way (ie if gnome is installed then open terminal).
For PtokaX compile you need gmake (tool controlling executable generation from sources), tinyxml (library used to read and write xml files), libiconv (converts text from one encoding to another encoding) and Lua (programming language used for scripting).
They can be installed using package manager (Note: to install packages using package manager you need root permissions).
