Attempting to follow those instructions, but this fails with many
messages like -

Failed to download horde/Horde_Vfs within preferred state "stable", 
latest release is version 1.0.0RC1, stability "beta", use 
"channel://pear.horde.org/Horde_Vfs-1.0.0RC1" to install

Do I have to install all those manually (specifying the full channel) or
is there a pear setting to get around this?  I understand it is beta, I
just want to tell pear that is OK.
