From what I can tell, it looks like you have installed some packages from remi's repo. If you have, then that could be very well why you are having issues. I don't include horde_lz4, but remi has built an rpm for it. Remi's PEAR-1.9.5 rpm broke things, so I don't use that either. I also don't include net_IDNA2, Numbers_Words, Text_Captcha, Text_Passwords. You will have to verify if you used files from him. A standard SME server 9 install with all updates works with no issues when adding horde in all tests I have done.
Thank you,
John
