spca5xx with 2.6.19

[Alexander Jede]

Hallo list
I have feisty installed with the kernel 2.6.19 on my AMD64.
Unfortunately I can't build the spca5xx modules for my webcam.
I get the following error if I run m-a or make:

   Building SPCA5XX driver for 2.5/2.6 kernel.
   Remember: you must have read/write access to your kernel source tree.
make -C /lib/modules/`uname -r`/build SUBDIRS=/usr/src/modules/spca5xx
CC=cc modules

Can anyone help me to build the module?

Thanks
