port of slapt-mod to porteux current

[beny]

hi porteux i have tried to port the script in porteux current but i have no luck, work all but the downloads and the script to build xzm not,so you have any hint to work with,i have gslapt that work well with the current repositories,but you know i want to follow something that work better. pmod work well, slapt-mod do not read package_data, but slapt-get can download all the files, ok just for the record
