I've built tcpcrypt in a demo system running debian unstable on amd64
(x86_64) from git commit f319e3e6ecd0159be949177fce0c0dc1b659dcfc.  But
i get the following error from the launch_tcpcryptd.sh:

root at sid:/home/dkg/src/tcpcrypt/tcpcrypt/user# ./launch_tcpcryptd.sh 
Tcpcrypting port 80 and 7777...

Any recommendations for what would be a useful next steps for debugging?
