Trouble installing on new server

[apowell]

Just set-up a new server and I am getting an error 500 when I try to view the installer:

FastCGI sent in stderr: "PHP message: PHP Fatal error: Class 'SimpleXMLElement' not found in /usr/local/www/admin/inc/basic.php on line 197" while reading response header from upstream, client: 10.2.1.105, server: localhost, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/run/php-fpm/php-fpm.sock:", host: "10.2.1.91"

Other PHP scripts are working fine and I can pull up phpinfo

Fixed it by recompiling php with simplexml support
Just for other people if you're having the same trouble, I use freebsd and I navigated to /usr/ports/lang/php5-extensions then did

make config [to rebuild the config]
make install clean ; rehash [to recompile the extensions]

Simexml is a requirement as stated on the download page.
