[horde] PHP Eaccelerator 0.9.6 breaks my Horde install

[Simon Wilson]

Doing a dummy run "pear upgrade -a -p -c horde" tells me (amongst  
other things!) that:

"horde/Horde_Cache can optionally use PHP extension "eaccelerator"  
(version >= 0.9.5)"

I use APC cache at the moment, and live with the occasional segfaults  
it gives by automatically restarting apache when it does it, so when I  
saw that I thought I'd install eaccelerator and see if it works better.

So - yum install php-eaccelerator installed  
php-eaccelerator-0.9.6.1-1.el6.x86_64 from EPEL repository. Cool I  
thought - that satisfies (version >= 0.9.5).

As soon as it is installed and apache restarted - Horde breaks with a  
500 error message in browser. Httpd error log messages include:

No change in Horde config, just stops working with it installed.  
Uninstall it and restart apache, Horde comes back to life.

I then noticed when you select eaccelerator on Horde Configuration  
Caching page it says that eaccelerator must be 0.9.5 or LOWER, stating  
"eAccelerator must be built with --with-eaccelerator-shared-memory at  
compile time to allow caching. WARNING: The cache functionality has  
been removed with eAccelerator version 0.9.6. If you want to use the  
eAccelerator cache driver, you need version 0.9.5 or lower."

So a question - Only 0.9.5 satisfies both the stated pear requirement  
message and the message stated on the config page... if the cache  
functionality has been removed with 0.9.6 then what else can  
Horde_Cache "optionally use > 0.9.5" for, or should that optional  
dependency be changed to be (version <= 0.9.5) instead of (version >=  
0.9.5)?

And that's beside wondering why just having it installed completely  
breaks my install... :)
