Is there a generally applicable idiom to check the existence and version
number of PHP libraries, much like we do for the gd extension (meaning C
extension, I presume):

  <?php if (!extension_loaded('gd')) { ... }

  if (isset($gd_info['GD Version'])) {
  $gd_version = $gd_info['GD Version'];
  $gd_version=preg_replace('%[^0-9.]%', '', $gd_version);
  if ($gd_version > "2.0") { ... }

If so, it would be great to put those in a concise script that is called
by 1checkSystem.php.

This would make it easier to update external
dependencies (without mucking with the PHP templates), and also to
inventory dependency requirements for distro packagers.
