The clue is above. You don't have 'so' called libipt_--string, it's 
called libipt_string.so

The correct syntax is :

iptables -t mangle -A PREROUTING -p tcp -m string "pepee" -j DROP

no offence Michael but I think you are wrong

it's -m string --string "string to match"

Incorrect. You specify the module you want to use with a '-m string' and then give it's parameter with a '--string "search this"'
