Mandrake 10.0, trying to install BCM(9)4306 Wireless card

Well what i mean by problem is i dunno what to do with it.

I do the usual uncompress and cd tot he directory, and in the help file it says the next step is: Make Install.

The response i get is:

make -C driver install
make[1]: Entering directory `/root/Desktop/ndiswrapper-0.10/driver'
make -C /lib/modules/2.6.3-7mdk/build SUBDIRS=/root/Desktop/ndiswrapper-0.10/driver
        EXTRA_VERSION= modules
make[2]: Entering directory `/lib/modules/2.6.3-7mdk/build'
make[2]: *** No rule to make target `modules'.  Stop.
make[2]: Leaving directory `/lib/modules/2.6.3-7mdk/build'
make[1]: *** [default] Error 2
make[1]: Leaving directory `/root/Desktop/ndiswrapper-0.10/driver'
make: *** [install] Error 2

It errors out.

Well, i guess i need a laymens walkthrough for this, as i do not get it.
