Error: Missing Dependency: php-common = 5.1.6-39.el5_8 is needed by package php-gd-5.1.6-39.el5_8.x86_64 (base)
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
