I have a VPS running Centos with Kloxo on and I was wondering how I would upgrade the PHP to 5.3 - It's currently running 5.2.6.

When I try and do a yum update I get the following errors:

    Resolving Dependencies
--> Running transaction check
--> Processing Dependency: libpq.so.4 for package: lxphp
---> Package postgresql-libs.i386 0:8.3.7-umask.7 set to be updated
--> Finished Dependency Resolution
lxphp-5.2.1-400.i386 from installed has depsolving problems
  --> Missing Dependency: libpq.so.4 is needed by package lxphp-5.2.1-400.i386 (installed)
Error: Missing Dependency: libpq.so.4 is needed by package lxphp-5.2.1-400.i386 (installed)
 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.

Any help would be greatly appreciated.
