the installed scripts use bash features. They should either have /bin/bash in the first line (easy fix) or be changed to run on sh.
Without the change one needs to manualy change it and create the database, as the script execution fails during installation.
It seems somthing has changed in bash in the last years. I'll see if I can get around to fix this.
Suprising that anybody still uses this :)
The problem is that the scripts where having /bin/sh in the first line, but using bash features. On most systems bash is also providing sh. This has the disadvantage, that those problems go unnoticed. Under e.g. ubuntu dash is providing sh and dash!=bash. So using bash explicitely would be fine and would fix the problem.
I was just about to report exactly the same issue -- you beat me by some... oh... years. ;-)
