Hello all!

When trying to build serialmonkeys rt61 drivers (I have a card not working with ndiswrapper you see) I get the following error after typing make in a terminal window:
Code:
make[1]: Entering directory `/usr/src/linux-2.6.25.5-1.1-obj/i386/default'
make[1]: *** No rule to make target `modules'.  Stop.
make[1]: Leaving directory `/usr/src/linux-2.6.25.5-1.1-obj/i386/default'
rt61.ko failed to build!
make: *** [module] Error 1
I have make, gcc and linux-kernel-headers installed. What is going wrong?

Thanks for all help!
