I have the same problem. As of about 1997-06-10 ppp doesn't seem to remove
the default route.  With log tcp/ip enabled the write in OsSetRoute fails
on the delete command. Have there been any changes to ppp that would
require changes to ppp.conf to delete the default route? A change to
route.c that seems to fix the problem for me is:

--- route.c.orig        Tue Jun 17 07:45:47 1997
+++ route.c     Tue Jun 17 07:28:36 1997
@@ -74,6 +74,7 @@
   rtmes.m_rtm.rtm_version = RTM_VERSION;
   rtmes.m_rtm.rtm_type = cmd;
   rtmes.m_rtm.rtm_addrs = RTA_DST | RTA_NETMASK | RTA_GATEWAY;
+  if (cmd == RTM_DELETE) rtmes.m_rtm.rtm_addrs &= ~RTA_GATEWAY;
   rtmes.m_rtm.rtm_seq = ++seqno;
   rtmes.m_rtm.rtm_pid = getpid();
   rtmes.m_rtm.rtm_flags = RTF_UP | RTF_GATEWAY | RTF_STATIC;

This is from route.c v1.13. It seems that RTM_DELETE doesn't work
for default if the addrs is declared as a gateway.
