This doc contains information on building the source tree with the Vyatta addons:

creating xorp image

> get a current copy of the xorp archive
> mkdir /usr/local/src/rl/main
> cd /usr/local/src/rl
> cp -r [root dir]/xorp/* /usr/local/src/rl/main
> mkdir /usr/local/src/rl_new
> cd ../rl_new
> svn checkout svn://69.59.150.134/rl/trunk/main
> cd /usr/local/src/rl
> cp -R ../rl_new/. .
> cd rl/main
> ./bootstrap;./configure;make
> cd rl_system
> g++ rl_cmds.cpp -o rl_cmds


Notes:
Somehow libtool is grabbed from the local system (and doesn't work with this build). So the old version needs to be copied over after bootstrap/configure is performed.

This build only works with the current xorp source and not v1.1 or earlier.
