This is an upstream issue. It seems, that gspcav1 1.00.20 doesn't work
with kernels > 2.6.26, as I've just read in a German forum.

The file semaphore.h is now located
in /usr/src/linux-2.6.30-fbcondecor/include/linux.

So the file gspca_core.c in the gspcav1-fbcondecor package needs to be
patched and "asm/semaphore.h" needs to be changed to
"linux/semaphore.h".

As a workaround you can add this line to your PKGBUILD:
sed -i "s:asm\/semaphore.h:linux\/semaphore.h" gspca_core.c

But you should also file a bug report to upstream, so that the gspca
developers can update the software, so that it compiles with kernel
2.6.27 and above.

Cheers,
Heiko
