OK I managed to progress.  The good news:  PHP is upgraded from 5.4 to  
7.2.  Horde feels snappier and much faster.  Also PDF's are OK now in  
IMP.

Bad news: I am still stuck with the original issue (not able to  
upgrade Horde).  The command "pear config-show" gives:

PHP extension directory        ext_dir          /usr/lib64/php/modules
Base Horde directory           horde_dir        /var/www/html/horde
PEAR directory                 php_dir          /usr/share/php
Systems manpage files          man_dir          /usr/share/man

While the command "pear config-show system" gives:

PHP extension directory        ext_dir          <not set>
Base Horde directory           horde_dir        <not set>
PEAR directory                 php_dir          /usr/share/pear
Systems manpage files          man_dir          <not set>
directory

So clearly there are difference between the variables.  If I run  
"whoami" in Horde's CLI webinterface, it reports "apache", so I  
believe Horde is running under the user "apache" which would make  
sense.  Apache's home folder seems to be "/usr/share/httpd" according  
to the following command"

[root at centos-mail[1] httpd]# getent passwd apache
apache:x:48:48:Apache:/usr/share/httpd:/sbin/nologin

There are NO .pearrc files in its "home" folder.

Do you still recommend symlinking or there's a cleaner way of putting  
things back in order?

Gettin' there!
