Ok. My next steps were like this:
1) I added to original gnap-portagesnapshot my wireless apps
(hostap-driver, hostap-utils, wireless-tools, quagga)
2) I had to add metadata for these apps (I am not familiar with portage)  :-)
3) Gnap_make ended with error libpcap was missing.
4) I added libpcap do portage and to matedata
5) Gnap_make went further. But next error appeared:

I have kernel.conf with my actual kernel config. How can I go on?
