This **notorious** ip_conntrack_pptp module failed to link due to
unresolved symbol, 

          __ip_conntrack_expect_find, 

there is a history of it in the maillist. I looked all over and I finally 
changed all references  ( actually there is only one reference ) to :-

          __ip_conntrack_exp_find

It happily linked now. Is this the right fix ?

Cheers.
