I get:

make[3]: Entering directory `/usr/local/src/xapian-bindings-0.9.2/php4'

Warning: dl(): Dynamically loaded extensions aren't allowed when running 
in Safe Mode in /usr/local/src/xapian-bindings-0.9.2/php4/smoketest.php 
on line 22

but can't see why it would be running in Safe mode, I don't have safe 
mode on in my php.ini.
