Running "yum update" for the first time in almost four weeks, I get the following errors: Error: Missing Dependency: gcc = 4.0.0 is needed by package libtool Error: Missing Dependency: openoffice.org-core = 1:1.9.104-2 is needed by package openoffice.org-pyuno Error: Unable to satisfy dependencies Error: Package mozilla needs mozilla-nss = 37:1.7.8-2, this is not available. Error: Package mozilla needs mozilla-nspr = 37:1.7.8-2, this is not available. Error: Package libtool needs gcc = 4.0.0, this is not available. Error: Package openoffice.org-pyuno needs openoffice.org-core = 1:1.9.104-2, this is not available. Any ideas what is going on here?
