Php – Debian PHP 5.3 APD compile problems

I've been trying to install APD on Debian using pecl install apd. However, the command fails when entering the make stage:

make
/bin/sh /src/apd-1.0.1/libtool --mode=compile cc  -I. -I/src/apd-1.0.1 -DPHP_ATOM_INC -I/src/apd-1.0.1/include -I/src/apd-1.0.1/main -I/src/apd-1.0.1 -I/usr/include/php5 -I/usr/include/php5/main -I/usr/include/php5/TSRM -I/usr/include/php5/Zend -I/usr/include/php5/ext -I/usr/include/php5/ext/date/lib  -DHAVE_CONFIG_H  -g -O2   -c /src/apd-1.0.1/php_apd.c -o php_apd.lo 
mkdir .libs

Downloading the source, phpizeing and compiling myself leads to the same thing.

And help with why this is and how to get around it would be much appreciated!
