Error upgrading Apache...

[SH Development]

I am getting the following error after running port -u upgrade outdated:

--->  Computing dependencies for apache2
--->  Verifying checksums for apache2
Error: org.macports.checksum for port apache2 returned: httpd-2.2.26.tar.bz2 does not exist in /opt/local/var/macports/distfiles/apache2
Please see the log file for port apache2 for details:
    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_www_apache2/apache2/main.log
Error: Unable to upgrade port: 1
To report a bug, follow the instructions in the guide:

This seems to have started since upgrade to Mavericks.

Thoughts?
