Make sure address negotiation is ON in /etc/ppp/options, and it might be
helpful to turn on debugging so that you can see the results of the 
LCP and IPCP negotiation when pppd is trying to set up the connection.

I have used PPP to connect to a dynamically assigned ip address and it's 
pretty straightforward.  I'm not even sure how you'd approach a dynamically
assigned address for a SLIP connection...

You can also use 'netstat -rn' to see if pppd is actually starting up and
installing the default route.
