Richard moved a stdarg.h include to database.hh just after
0.21, does that fix it?

It should bomb out with an error message, probably printed
above the discarded packet warnings. If your network
connection is having timeout problems (the ssh problems you
mentioned), it's possible that there isn't any data
transferred for long enough that the connection times out,
and monotone fails. Are you going through any strange
routers etc? The error message would be useful.

I'm not too sure, though googling suggests that it's a boost
error in the bsd config file, see
http://lists.freebsd.org/pipermail/freebsd-ports-bugs/2005-January/050580.html

Are you using a boost port from after mid-February?

The /dev/urandom file is a special device, you'll need to create it with 
mknod /var/www/dev/random  c  2 3
or something similar (those device numbers may be wrong, I just googled).

You can run it just from startup scripts, though it's useful
if it's running under some some sort of supervisor program
which can restart it if it stops running for some reason.
Nathaniel's docs are at
http://frances.vorpus.org/~monotone/netsync-setup.html ,
though that uses runit - I'm not sure of standard
alternatives on BSDs. Also note that the permission hook
format has changed since that was written.
