I retried the build earlier and this is the second time it's happened today so it doesn't appear to be a transient issue.

Last successful build was yesterday: https://code.launchpad.net/~strongswan/+archive/strongswan-daily/+builds?build_text=&build_state=all of commit ID b517912848734f81d31161b47db1451939456cc5.
