[horde] I can't install SyncML and XML_WBXML

[Alexa Rodríguez]

Hi!

Excuseme my english.

I'm trying install SyncML and XML_WBXML way "pear", but I could not.
I follow  the instructions  the next web page: 
http://wiki.horde.org/SyncMLCustomBackend.

Versions of installed packages are: S.O debian etch,  php-pear   
5.2.0-8, php5   5.2.0-8.

Here is the result of the command "pear list":

Installed packages, channel pear.php.net:

These are the steps I have followed

1. pear channel-discover pear.horde.org

2. pear install horde/SyncML         
Failed to download horde/SyncML within preferred state "stable", latest 
release is version 0.0.4, stability "alpha", use 
"channel://pear.horde.org/SyncML-0.0.4" to install
Cannot initialize 'channel://pear.horde.org/SyncML', invalid or missing 
package file
Package "channel://pear.horde.org/SyncML" is not valid
install failed

3. pear install horde/SyncML-0.0.4
horde/SyncML requires package "pear/XML_WBXML"
No valid packages found
install failed

Then try

4.  pear install horde/XML_WBXML  
Ignoring installed package horde/XML_WBXML
Nothing to install

Or

5. pear install XML_WBXML
No releases available for package "pear.php.net/XML_WBXML"
Cannot initialize 'channel://pear.php.net/XML_WBXML', invalid or missing 
package file
Package "channel://pear.php.net/XML_WBXML" is not valid
install failed

What's the problem ?
