Creación de Graphviz de biblioteca estática para iPhoneOS. ¿Qué guión?

Estoy desesperado: (He probado todo tipo de scripts y ninguno funciona. Mi sistema es xCode4.3.2 en Lion (10.7.4) con iOS-SDK v5.1

Con el guión:

#!/bin/sh
# For iPhoneOS, see http://clang.llvm.org/ for options
export DEV_iOS=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer
# was /Developer/Platforms/iPhoneOS.platform/Developer
export SDK_iOS=${DEV_iOS}/SDKs/iPhoneOS5.1.sdk
export COMPILER_iOS=${DEV_iOS}/usr/bin
export CC=${COMPILER_iOS}/clang
export CXX=${COMPILER_iOS}/clang++
export LDFLAGS="-arch armv7 -pipe -Os -gdwarf-2 -mthumb -isysroot ${SDK_iOS}"
export CFLAGS="${LDFLAGS}"
export OBJCFLAGS="${LDFLAGS}"
export CXXFLAGS="${LDFLAGS} -fvisibility-inlines-hidden"
export LD=${COMPILER_iOS}/ld
export CPP=${COMPILER_iOS}/clang
export AR=${COMPILER_iOS}/ar
export AS=${COMPILER_iOS}/as
export NM=${COMPILER_iOS}/nm
export CXXCPP="${COMPILER_iOS}/clang++"
export OBJC=${COMPILER_iOS}/clang
export RANLIB=${COMPILER_iOS}/ranlib

./configure \
    --build=arm-apple-darwin11 \
    --host=arm-apple-darwin11 \
    --disable-dependency-tracking \
    --enable-shared=no \
    --enable-static=yes \
    --enable-ltdl=no \
    --enable-swig=no \
    --enable-tcl=no \
    --srcdir=${GVROOT} \
    --with-codegens=no \
    --with-cgraph=no \
    --with-graph=yes \
    --with-expat=no \
    --with-fontconfig=no \
    --with-freetype2=no \
    --with-ipsepcola=yes \
    --with-libgd=no \
    --with-quartz=yes \
    --with-visio=yes \
    --with-x=no

Me sale el error:

¿Alguien puede decirme qué script puedo usar en mi sistema (XCode4.3.2 - iPhoneSDK5.1 - Lion 10.7.4) para obtener la biblioteca estática Graphviz para IOS.

Muchas gracias.
