[SOLVED] makeing a current iso using 14.2 missing xorriso

Hi, I thought it was about time i tried current on something as 15.0 is due, and reading the isolinux/README.TXT it gives an example of how to create an iso when you have the directory tree. Unfortunately it uses xorriso which is not in 14.2 or on slackbuilds. I tried installing xorriso from current intself onto 14.2 in order to create the iso, but it complains about libreadline.so.8 being missing, and I tried adjusting the creation command by replacing Code:xorriso -as mkisofs with just Code:mkisofs but it complains about one of the options. ( -isohybrid-mbr ).

Can anynoe point me to the recommonded way of creating a "current" iso from a "14.2" installation?
thanks.
