Allow building with Homebrew's ````apxs```` (#401, #437)
BUGFIX: Compiling php52 against mysqlnd fails, fix this by compiling against mysql_config in php52. Shift code that builds args from "_install" to "install_args" to allow the overwriting of default options in extending classes
MINOR: No need to delete and re-add socket path
Added a note to update installed formulae when possible. Closes #436
add libvirt 0.4.7 extention
