There is a bothersome bug that messes up the xml parser for php apps in libxml 2.7.2 - we have a new centos 5 box with php 5.2.6 and apache 2 over at serverbeach and came across this problem. Unfortunately version 2.7.2 of libxml2 is part of the STABLE branch. bug reported at http://bugs.php.net/bug.php?id=45996&thanks=3 How can we rebuild to go back to a previous version that does not have this bug? We have the tarball for 2.6.22 but are afraid running the build and configure will break something else. We also have the rpm for the older version and noticed older versions are on the system already (2.6.26) and apprear to be built but not sure how to get them running in place of the more recent stuff. Can someone shed some light?
