realtime kernel build w/ abs

OK...I'm close! I got a package to build, but even though I changed EXTRAVERSION from -ARCH to -RT I get this error when trying to install:

kernel26rt: /usr/src/linux-2.6.21-ARCH/include/sound/cs46xx_dsp_scb_types.h: exists in filesystem
kernel26rt: /usr/src/linux-2.6.21-ARCH/include/sound/cs46xx_dsp_spos.h: exists in filesystem

etc. forever.

I did make menuconfig and I know I changed it...for sure.

PKGBUILD:

pkgname=kernel26rt
_basekernel=2.6.21
pkgver=2.6.21.1
pkgrel=1
pkgdesc="The Linux Kernel and modules + RT patchset"
arch=(i686)
url="http://www.kernel.org"
backup=('boot/kconfig26' etc/mkinitcpio.d/${pkgname}.preset)
depends=('module-init-tools' 'mkinitcpio>=0.5.13')

install=kernel26.install

    cp -a include/$i $startdir/pkg/usr/src/linux-${_kernver}/include/

etc...

copied from kerenel26 from here out.

Maybe I have to do more editing in the build dir?

Thanks
