Been using modp1024 and that's what vpnc settles on.  But, isn't modp
just phase1 for the initial IKE key exchanges?

If it is both phase1 and phase 2, we've got another problem.  As soon as
I still more than one proposal in the phase2alg= param that has modp
parameters the libraries are hurling stack smashing hunks at me...

Yeah, I know...  All that cruft is in the libnss stuff.  Don't get me
started.  I'm giving THAT the Scarlet O'Hare treatment (Gone With The
Wind) and saying I'll worry about THAT tomorrow.

If I don't specify any modp params to phase2 I can load'm up.  But...
Maybe it's not doing anything and not telling me?

I can rebuild without the nss stuff and cut that out of the confusion
factor as well.
