Modify the Debian packaging files to provide the correct compilation options - sorry I'm not experienced with this as I've only made RPMs before =- but it should be pretty easy to figure out.
On a karmic box:
$ apt-get source libfreetype6
$ grep -h TT_CONFIG_OPTION_BYTECODE freetype-2.3.9/debian/patches-freetype/*
-/* #define TT_CONFIG_OPTION_BYTECODE_INTERPRETER */
+#define TT_CONFIG_OPTION_BYTECODE_INTERPRETER
