When running the following command I ended up getting errors that phpize was missing. Trying to dig into this further i found that configure.ac was just trying to run php-config without providing a path. The following patch corrects the issue by using the $PHPCONFIG variable instead.
./configure --prefix=/opt/libvirt-php --with-php-config=/path/to/php-config`
diff --git a/configure.ac b/configure.ac
