You know, the reason is I want to set up access point with my RaLink Card
After some googling i stubled upon rt2x00 driver forum, where folks say I have to get hostapd and libnl (for mac80211)
I think the reason for libnl is exactly my chip:
>crystal at Crystal:~/OperaDownloads/hostapd-0.6.8/hostapd$ lspci | grep Ra
>02:03.0 Network controller: RaLink RT2561/RT61 rev B 802.11g

Anyway, I corrected the environment and that nasty error faded away, though I get another one

>crystal at Crystal:~/OperaDownloads/hostapd-0.6.8/hostapd$ /usr/local/bin/hostapd -ddB /etc/hostapd/hostapd.conf
>Configuration file: /etc/hostapd/hostapd.conf
>Line 44: DEPRECATED: 'debug' configuration variable is not used anymore
>ioctl[PRISM2_IOCTL_PRISM2_PARAM]: Operation not permitted
>Could not enable hostapd mode for interface wlan0
>hostap driver initialization failed.
>wlan0: Unable to setup interface.
>rmdir[ctrl_interface]: No such file or directory

Why the hell it thinks I have Prism??
