Freebsd 7.2 & firefox3

[Maxx]

Hello,

I`ve got the problem with installing firefox3:

checking for DRIGL... gnome-config: not found
gnome-config: not found
configure: error: Package requirements (x11 xext xxf86vm xdamage xfixes 
x11-xcb xcb-glx) were not met:

No package 'x11-xcb' found
No package 'xcb-glx' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

See attached file for more info. Is this bug?

Best regards, Maxx.
