[request | incomplete new] cinerella 2.0

Question

i have been able to compile and use cinerella 2.0 but i have not been able to make it a package
pkgname=cinelerra
pkgver=2.0
pkgrel=1
pkgdesc="2000 watt flame thrower or impossible to use video NLE"
license="GPL"
depends=('mjpegtools x-server libdv libavc1394 ffmpeg e2fsprogs libtheora openexr')
makedepends=('nasm yasm')
source=("http://internap.dl.sourceforge.net/sourceforge/heroines/$pkgname-$pkgver-src.tar.bz2")
#md5sums=('2aa64df684421c81fc63521d529e51f6')
build() {
cd $startdir/src/$pkgname-$pkgver
./configure --prefix=/usr --sysconfdir=/etc
make || return 1
make DESTDIR=$startdir/pkg -f build/Makefile.cinelerra install
it seems to ignores DESTDIR
--also i took the depends from cinerella-cvs, i don't know if more/less is required
also requires yasm
pkgname=yasm
pkgver=0.4.0
pkgrel=1
pkgdesc="Yasm is a complete rewrite of the NASM assembler"
license="various"
#depends=('')
makedepends=('')
source=(http://www.tortall.net/projects/yasm/releases/yasm-$pkgver.tar.gz)
md5sums=('2360e20c4e105ba95f4e9135a7901183')
build() {
cd $startdir/src/$pkgname-$pkgver
./configure --prefix=/usr --sysconfdir=/etc
make || return 1
make DESTDIR=$startdir/pkg install

Answer 1

i tried prefix (and editted the prevous post only to see you asked)
i've been combing through the make files, but i don't really know whats going on
and the files seem to be a few lines calling another file which calls another etc.
running
$cat * | grep -v cpp | grep cp -C2
  in the build dir shows that at least two of the smaller things are hardcoded(?) to /usr/bin/ 
for example
cp $(OBJDIR)/soundtest  /usr/bin/
$cat * | grep /usr/bin
cp $(OBJDIR)/soundtest usr/bin/
rm /usr/bin/mix2005
cp mix/$(OBJDIR)/mix2005 /usr/bin
thanks
