The file is not there and I tried to create it from the code in aolserver and did not work. It asks for libxml2, which is already installed. The aol version I have is 3.X (don't remember exactly which) and was pre-packaged with all the requirements of OpenACS. The suse 9.0 installation I have was done in a blank machine, no upgrades of operating systems. I basically formatted my machine and re-install (long story there...) Anyway, I did not loose the data I had but I'm reinstalling OpenACS again.
