Upgrading PHP v Redhat-u

Jst mam pa en manjsi problem.. Ko sem postaulau svoj server sm si pomagal z YUMom in enostavno napisal "yum install php" Leta mi je nalozil verzijo 4.2.2, ki pa je sccasoma zastarela zato bi rad zadevo pododobil.. Problem je v tem, ker nekatere stvari v sistemu potrebujejo staro verzijo PHPja in problem se v tem, da yum noce najdt novejse verzije.. Poskusam z "rpm -U php-4.3.10-2.4.i386.rpm" samo mi vn vrze error:

php = 4.2.2-17.2 is needed by (installed) php-mysql-4.2.2-17.2
php = 4.2.2-17.2 is needed by (installed) php-imap-4.2.2-17.2
php = 4.2.2-17.2 is needed by (installed) php-ldap-4.2.2-17.2

Kaj storiti? Ma se neke probleme z dependecies kot recimo:

httpd-mmn = 20020903 is needed by php-4.3.10-2.4
libaspell.so.15 is needed by php-4.3.10-2.4
libc.so.6(GLIBC_2.3.4) is needed by php-4.3.10-2.4
libdb-4.2.so is needed by php-4.3.10-2.4
libpspell.so.15 is needed by php-4.3.10-2.4
php-mbstring = 4.3.10-2.4 is needed by php-4.3.10-2.4
php-pear is needed by php-4.3.10-2.4

sam to itk ni panike..

Kako nej updejtam/upgrejdam (kje je razlika v tem?) da bo zadeva funkcionalna?
