[horde] Upgrading: Some things won't install

[cjdl01]

Hi, I upgraded today to the most current version of horde  
(turba-3.0.15, kronolith-3.0.17, gollem-2.0.2, ingo-2.0.9,  
horde-4.0.15, imp 5.0.23, mnemo 3.0.6 and nag-3.0.8).

I am using debian squeeze, and everything is stable and up to date as  
of today.

I did my pear upgrage PEAR

then my pear upgrade -a -B -c horde


Most of the upgrade seemed to go well, but there were some packages  
that refused to install:

Failed to download horde/Horde_Date within preferred state "stable",  
latest release is version 2.0.0beta2, stability "beta", use  
"channel://pear.horde.org/Horde_Date-2.0.0beta2" to install
Failed to download horde/Horde_Exception within preferred state  
"stable", latest release is version 2.0.0beta1, stability "beta", use

3.0.0alpha1), installed version is 1.0.2
horde/Horde_Ldap requires PHP extension "ldap"
No valid packages found
upgrade failed

When I try to explicitly upgrade a package, it tells me there is  
nothing to do:

# pear upgrade channel://pear.horde.org/Horde_Date-2.0.0beta2
Nothing to upgrade

So, I don't see a way to install these...  I'm not great with pear, so  
maybe I'm missing something...


Also The other non-stable package dependencies... I'm not sure how to  
install them, I am hoping someone can give me a pointer there...

Thank you for the help.
