Ios 在xcode中配置脚本失败，退出代码为1

我正在以Xcode运行脚本的形式运行此脚本，以构建graphviz：

if [ ! "${BUILT_PRODUCTS_DIR}/graphviz/Makefile" -nt "${SRCROOT}/graphviz/configure" ]
then
  GVROOT="${SRCROOT}/graphviz"

  # figure out optimization
  OPT="${GCC_OPTIMIZATION_LEVEL}"
  if [ -z "${OPT}" ]
    then
    OPT="s"
  fi

  FLAGS="-fexceptions -gdwarf-2 -isysroot ${SDKROOT} -miphoneos-version-min=${IPHONEOS_DEPLOYMENT_TARGET} -mthumb -O${OPT}"

  # figure out architecture
  for ARCH in ${ARCHS}
  do
    FLAGS="${FLAGS} -arch ${ARCH}"
  done

  # figure out preprocessor defines
  for DEFINITION in ${GCC_PREPROCESSOR_DEFINITIONS}
  do
    FLAGS="${FLAGS} -D${DEFINITION}"
  done

  mkdir -p ${BUILT_PRODUCTS_DIR}/graphviz
  cd ${BUILT_PRODUCTSx_DIR}/graphviz

  ${GVROOT}/configure \
    --build=${NATIVE_ARCH_ACTUAL}-apple-darwin11 \
    --host=${NATIVE_ARCH}-apple-darwin11 \
    --disable-dependency-tracking \
    --enable-shared=no \
    --enable-static=yes \
    --enable-ltdl=no \

    --with-libgd=no \
    --with-quartz=yes \
    --with-visio=yes \
    --with-x=no \
    CC="${PLATFORM_DEVELOPER_BIN_DIR}/clang" \
    CPP="${PLATFORM_DEVELOPER_BIN_DIR}/clang -E" \

    OBJC="${PLATFORM_DEVELOPER_BIN_DIR}/clang" \
    LD="${PLATFORM_DEVELOPER_BIN_DIR}/ld" \
    CFLAGS="${FLAGS}" \
    CXXFLAGS="${FLAGS} -fvisibility-inlines-hidden" \
    OBJCFLAGS="${FLAGS}" 2>/dev/null
fi

我得到以下编译器输出：

checking build system type... x86_64-apple-darwin11
checking host system type... i386-apple-darwin11
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes

如何找出哪里出了问题？

我通过以root用户身份运行Xcode找出了哪里出了问题。这给了我更多详细的失败消息（不知道为什么）。我的问题是我需要“makedistclean”，因为我在目录中有一个以前的版本
