OK.

I just copied it as discussed in the original mail to avoid that make 
install kills the 8.4 production RPM version:
cp ./src/backend/postgres /bin/postgres-8.3.11

cd /bin
ln -s /usr/share/pgsql/timezonesets share
cd tarballdir
./configure
make
cp ./src/backend/postgres /bin/postgres-8.3.11

I previously made the strace and therefore I added the option to configure 
to get the right directory.

Any further idea where I should copy the binary or any option or any file 
copy for the time zone files?

Thnx.

Ciao,
Gerhard
