[horde] webmail-install missing after install

[Cliff Hayes]

I am attempting to reinstall horde.  I did the following to uninstall:
deleted everything in /var/www/html/horde
pear uninstall horde/horde_role
pear uninstall `pear list -c horde | tail -n +4 | awk '{ print 
"horde/"$1 }'`
pear channel-update pear.php.net
pear clear-cache
And now, when I run the install as follows, it never creates a 
webmail-install:
pear channel-discover pear.horde.org
pear install horde/horde_role
pear run-scripts horde/horde_role
pear install -a -B horde/horde
