Hi snake, thanks for the link. I got so far as updating the bridge firewall rules and realised i was out of space - odd as everything is on USB storage... except TCPdump. Anyway after moving that to USB SSLStrip has just installed fine.
This is very odd as I've tried installing SSLStrip numerous times today to USB prior to other things being installed and it didn't work.
Is the installation of SSLStrip dependant upon the installation of any other infusions? Not that it matters, it's running... typically straight after I posted!
Cheers
