I am trying to upgrade Php 5.1 to 5.2, I have added a few repos for yum, but I end up getting two errors: Missing Dependency: libldap-2.3.so.0 is needed by package php-ldap Missing Dependency: liblber-2.3.so.0 is needed by package php-ldap I have openldap 2.4 installed, libldap-2.4.so.2.2.0 and liblber-2.4.so.2.2.0 are present. I know that I could link to these files correct? But would that break any compatibility? Any advice how I can proceed would be really helpful.
