Perhaps a bit farther:

Checking for C library curses... yes
Detected libraries: boost_regex rt resolv crypto dl pcap curses
Symlink("/home/greearb/git/xorp.ct/obj/x86_64-unknown-linux-gnu/lib", as "/home/greearb/git/xorp.ct/obj/x86_64-unknown-linux-gnu/lib/xorp/lib")
OSError: Target does not exist: /usr/local/xorp/lib/xorp/lib:
   File "/home/greearb/git/xorp.ct/SConstruct", line 644:
     env.Dir('$xorp_sbindir').abspath))
   File "/home/greearb/git/xorp.ct/relpath.py", line 12:
     raise OSError, 'Target does not exist: ' + target
