Need help with ndiswrapper

[Patrick McCarthy]

Hi,
I'm new to Linux and need a little help installing ndiswrapper.  I've
installed FC4 on my desktop and downloaded updates with Up2date.  I have
been unable to get my linksys WMP54Gv.4 wireless card recognized by the
network wizard.  I have downloaded ndiswrapper in order to install the
windows xp driver for the card, but am having trouble following all the
install instructions on the ndiswrapper
website-http://ndiswrapper.sourceforge.net/mediawiki/index.php/Installation

I used the 
ln -s /usr/src/linux-<kernel-version> /lib/modules/VERSION/build command
to build a link to the source, inserting '2.6.11-1.1396_FC4' as the
version.  
The next step went o.k.-'make distclean' in the ndiswrapper-1.2
directory, but the 'make' command produced a 'no link' error.  Sure
enough, upon clicking the /lib/modules/2.6.11-1.1369_FC4/build and
source files it said there was no link.
How do I find out if I have the source.  If not, how do I get it? 
What is 'the source'. Why wouldn't it have been installed with FC4?
Thanks,
Patrick
