After updating HEAD to around r187816 (I'm still using CVS), I get the
following on my laptop (which makes an attempt to use wpa_supplicant):

My build machine -- which does not attempt to use wpa_supplicant
-- is using a copy of the same sources, did not show a problem, and
had no trouble with its (fxp) NIC:
freebeast(8.0-C)[1] uname -a

freebeast(8.0-C)[3]=20
And it shows that wpa_supplicant was rebuilt today:
freebeast(8.0-C)[3] ls -lT `which wpa_supplicant`
-r-xr-xr-x 1 root wheel 272248 Jan 28 09:43:25 2009 /usr/sbin/wpa_suppli=
cant
freebeast(8.0-C)[4]=20
Since I used the same sources for each machine, and the same commands
to perform the source upgrade (from yesterday's HEAD), I believe
wpa_supplicant on the laptop was also updated today, per Sam's
message.
Peace,
david
