'Unknown symbol usb_kill_urb'

I've been trying to get a PRISM 2.5 USB wireless device to work in this thread:

After a lengthy process that eventually seemed to install the driver successfully, I now get errors trying to start it:

But when I run /etc/init.d/wlan start ...

[root@localhost dpiepgrass]# /etc/init.d/wlan start
Starting WLAN Devices: FATAL: Error inserting prism2_usb (/lib/modules/2.6.5-1.358/linux-wlan-ng/prism2_usb.ko): Unknown symbol in module, or unknown parameter (see dmesg)
[root@localhost dpiepgrass]# [ OK ]

...I figured I'd reboot to see if the init procedure would happen on startup. During bootup, a different error message came out, which was approximately:

usb_prism2 device wlan0 does not seem to be present. Delaying initialization.

I looked through dmesg's output and found

usb 1-1: new full speed USB device using address 2
prism2_usb: Unknown symbol usb_kill_urb

The latter message,

prism2_usb: Unknown symbol usb_kill_urb

appears several times in the file, but only once adjacent to that usb1-1 message, which seems to indicate the device is recognized (there is only one usb device attached, and that is the wireless thingie)
So, can anyone explain these errors?
