SPCA50X USB Camera Linux Driver

I trying to run Logitech webcam, especially with Skype. The output of
kgspca.err is:

make -C /lib/modules/`uname -r`/build SUBDIRS=/home/blair/gspcav1 CC=cc
modules
make[1]: Entering directory `/usr/src/linux-headers-2.6.28-13-generic'
scripts/Makefile.build:46: *** CFLAGS was changed in
"/home/blair/gspcav1/Makefile". Fix it to use EXTRA_CFLAGS. Stop.
make[1]: *** [_module_/home/blair/gspcav1] Error 2
make[1]: Leaving directory `/usr/src/linux-headers-2.6.28-13-generic'
make: *** [default] Error 2

Ideas?

The entire output in terminal was:

oot@ham:/home/blair/gspcav1# ./gspca_build

REMOVE the old module if present
ERROR: Module gspca does not exist in /proc/modules
