Thanks, that resolved the issue.
Building matching PHP was finally successful this time.
One more question, is when I was using this console menu option to build matching PHP, there was add-ons which are not normally listed on the home page "build matching PHP" default ticked or selected was "indetify PHP mail header" and other three eaccelerator, xchache & memcahe were un-checked.
I'm using eaccelerator on this server and was not sure if I should have ticked that option, therefore since I did not select. Believe I can still enable from one of the console menu options, right?
