Hi,

I am trying to upgrade php to version 5.   When running yum upgrade I 
get this failure:

--> Running transaction check
--> Processing Dependency: php = 4.3.9-3.22.9 for package: php-pear
--> Finished Dependency Resolution
Error: Missing Dependency: php = 4.3.9-3.22.9 is needed by package php-pear

but the required php version is installed:

[root at ftp ~]# rpm -q php
php-4.3.9-3.22.9


Any suggestions on what is wrong and how to fix this?

Thanks!

Ed
