Makepkg whont "install" the files to the pkg/ dir

Question

hi
this is my first PKGBUILD i made so far, but it whont work.
my problem is that makepkg whont copy the files to the pkg dir so it can make the package, instead it trys to install the files directly to the destination where they are supposed to be installed with the package manager.

make lang
make maps
cd base
./archives.sh
cd ..
make DESTDIR=$startdir/pkg/ install
cp -t $startdir/pkg/usr/share/ufoai/base/ base/*.pk3 base/*.cfg base/*.txt
"DESTDIR" whont works for me at all.
if i make
./configure --prefix=$startdir/pkg/usr
it trys to read the pk3 files from thet directory AFTER installing, so it whont work if i delete the pkg and src dir.

thank you for that hint.
i THINK i found why it is thatway(just wana state here that i am still an absolute newb in making PKGBUILD's my own).
there are some entrys in the MakeFile that describe where to put what (afaik because of what i gave ./configure as parameters?)
everything except the DATADIR is set to ${prefix}/bla or ${exec_prefix}/bla.
but DATADIR needs an absolute path as target to install probably or it gets just ignored, so its, whatever i make either DATADIR=/usr/share/ufoai(where i trys to install it there instead of throwing it into the pkg dir) or DATADIR=/home/bla/pkg/usr/share/ufoai(where he trys to look for that files even after installation.)
since i dont solved the problem with your hint i postet the makefile into a pastebin, maybe u can tell how to actually work around this.
