Exactly same versions. Good.

You are using 2.4.18-bf2.4 and the installed kernel source is 
132114=2.4.18. Very good.

The driver compiles--good.

But the driver doesn't match to the kernel. Bad.

The running kernel and the source must be configured 
differently because it fails. You must configure kernel source so that it 
matches the running kernel.

I think the easiest way is to copy the kernel configuration file of the 
running kernel to the kernel source directory, and configure it with that.
Do this:
 	cp /boot/config-2.4.18-bf2.4 \
 	   /lib/modules/2.4.18-bf2.4/build/.config
 	cd /lib/modules/2.4.18-bf2.4/build/
 	make oldconfig
and try then compiling qc-usb again.

Another possibility is to install the correct header package, in this case
 	apt-get install kernel-headers-2.4.18-bf2.4
it should be sufficient for compilation (instead of the kernel full source)
and preconfigured correctly. You just need to tell quickcam.sh
the header location with the LINUX_DIR option.
