I've further deduced I might be able to solve my problem with mpd instead  
of ptppclient. I still can't connect though and I'm unsure why.

My mpd.conf file:
vpn:
         new -i ng0 vpn vpn
         #set iface disable on-demand
         #set iface addrs 192.168.1.1 192.168.2.1
         set iface idle 0
# disconnect the client after 8 hours
         set iface session 28800
         set iface route default
         set bundle disable multilink
         set bundle authname "username" #Yes, I changed these from the  
defaults ;)
         set bundle password "password"
         set link yes acfcomp protocomp
#       set link no pap
         set link enable chap
         set link mtu 1460
# If remote machine is NT you need this..
#       set link enable no-orig-auth
         set link keep-alive 10 75
         set ipcp yes vjcomp
#       set ipcp ranges 192.168.1.1/32 192.168.2.1/32
#
# The five lines below enable Microsoft Point-to-Point encryption
# (MPPE) using the ng_mppc(8) netgraph node type.
#
         set bundle enable compression
         set ccp yes mppc
#       set ccp yes mpp-e40
         set ccp yes mpp-e128
         set bundle enable crypt-reqd
         set ccp yes mpp-stateless
         open

My mdb.links file:
vpn:
         set link type pptp
         set pptp self roscar.dyndns.org
         set pptp peer vpn.ubc.ca
         set pptp enable originate incoming outcall

When I run the command 'mpd vpn' I get the following output:

I'm sure there is some fault on my end, but my inexperience is blinding  
me. hopefully this more detailed assesment will get a response.
