Hey Schturman,

There is a bug at Powerpack and m4asupport installation. Basicly unzip (from powerbusybox) does not known the -u option in your script:

Basicly
PowerPack packages downloaed successfully...
unzip: invalid option -- 'u'
BusyBox v1.21.0 (1.21.0power1+harmattan0) multi-call binary.

Usage: unzip [-lnopq] FILE[.zip] [FILE]... [-xFILE...] [-d DIR]
