In the minimum installed Debian GNU/Linux there is no directory /usr/lib/systemd/system and installer fails during execution function installSystemdCtrlFiles from the scripts/postinstall.sh. I suppose, it will fail in any other environment with systemd and without that particular directory. This can be improved by changing the first line of mentioned function into something like

if systemdPresent && `mkdir -p $SYSTEMD_DIR`

Installer also will fail on a systems without installed libtommath package. This is more tricky, of course. However I suppose, it might be possible to write a function checkForRequiredPackages using something similar to commented checkForRPMInstall in the end of the scripts/preinstall.sh. Combining it with that "very beautiful but unused"(c)AP 2005 :) detectDistro, we can write something like that:

checkForRequiredPackages()
{
if [ detectDistro == 'Debian' ]
then
checkForDebInstall libtommath0
elif [ detectDistro == 'RH' ]
checkForRPMInstall libtommath
then
elif [ detectDistro == 'SuSE' ]
then
checkForYastInstall libtommath
fi
}

In the case maintainer will find this approach usefulness at least some kind of warning about this non-standard (because it does not installed in the typical linux environment) package would be helpful.
