If your 9front system is current, the new packages should appear in
the output of pkg/list.
If not, the package files are available here:
http://plan9.stanleylieber.com/pkg/386/rc-httpd-2012.01.07.tbz
http://plan9.stanleylieber.com/pkg/386/werc-2012.01.07.tbz
To install manually, unpack the package files in /, then edit the
appropriate config files.
