Talk:Peer Installation

Ran wikid on OS X using

/Users/svenbot/peer/wikid svenbot --start --dir=/Users/svenbot/peer
svenbox.log indicates some perl modules missing, HTTP/Request.pm, Date/Parse.pm

Ok, installed the modules, log file looks ok, and peer is logging into localhost wiki --Sven 00:43, 2 Apr 2007 (NZST)

Wikid - that's 99% of the difficulty out of the way then - gonna hit da sack now I reckon :-O

following the instructions, i installed it to http://www.div0.com/peer/peer.pl

and got 500 Internal Server Error

I chmod +744 and havesame problem.

Trying a differnt interpretation of the instructions, i also installed to http://www.div0.com/cgi-bin/peer.pl

here is the peer.pl that i downloaded:
