building mac80211

[John George Wright <john@limongrafica.com>]

Hi,

I'm very new to the linux operating systems so please treat me as a
child.

I have an Intel PRO/Wireless 3945ABG built into my laptop and I am
trying to adapt the latest version of ubuntu to work with it. I followed
some online instructions and downloaded the mac80211-10.0.4 tar,
unpacked it and used this command:

make SHELL=/bin/bash

but received the following error:

Building modified version in 'modified/' directory:

Would you have any idea where I'm going wrong?

Thanks,
