Here's a little PHP script you can put in your document root to see what the
environment variables are for apache. If you don't have access to httpd.conf
your going to have trouble unless you can install your shared libraries in a
path apache already knows about.
<?php
$vars = Array('GET', 'POST', 'COOKIE', 'SERVER', 'ENV', 'REQUEST', 'SESSION');
$php_version = preg_replace("/[^\d]/", '', phpversion());
for($i=0; $i<sizeof($vars); $i++) {
echo "<h1>HTTP_{$vars[$i]}_VARS</h1>";
if(is_array(${"HTTP_{$vars[$i]}_VARS"})) {
echo '<table border=1>';
foreach(${"HTTP_{$vars[$i]}_VARS"} as $var=>$val) {
echo "<tr><td>$var</td><td>$val</td></tr>";
if($php_version<410) {
$GLOBALS["_{$vars[$i]}"][$var] = $val;
}
unset($$key);
}
echo '</table>';
}
unset(${"HTTP_{$vars[$i]}_VARS"});
}
?>

I did. There's about six of them. I don't have access to the Apache config
files.

Try "locate libgdal" which should show you where all copies of files
with libgdal in the name are located on your system.
