Honestly I don't remember what I did to "hose" my system. I was getting a sysmon error on boot and I couldn't login over ssh to my box. I've been meaning to upgrade/rebuild so I figured it be easiest to do it.
I rebuilt my server with SME 6.0 Beta 3 + updates. From what I can tell, I successfully upgraded PHP to 4.3.3 using the RPM's Dan provided (THANKS!).
PHP RPMS USED:
--------------------------
| ---> php-4.3.4-1db.i386.rpm
| ---> php-imap-4.3.4-1db.i386.rpm
| ---> php-ldap-4.3.4-1db.i386.rpm
| ---> php-mysql-4.3.4-1db.i386.rpm
| ---> php-devel-4.3.4-1db.i386.rpm
Then in directory:
#rpm -fvh *.rpm
(Note: I got an warning message here; saying php.ini was created as php.ini.rpmnew -- this was removed by the system by expanding the template below)
Then to fix IMP (Again, Thanks Dan)
# pear install Log
# /sbin/e-smith/expand-template /etc/php.ini
I didn't use the "sme56_imp-horde-php_upgrade.htm" howto because SME6.0 has newer version of horde already installed and the PHP rpms were 4.3.2.
Don't know if I did this "right" or not but it seems to be working with everything.
