The rebuild script just nets me an 'undefined modules' error

[Gensoukyou1337]

I wanted to rebuild the Android-ImageMagick library, but with modified files from jmagick's misc repo containing the distortImage functionality. My problem is that with the rebuild script as is (though with the first line being changed into export NDK=<NDK path>), it just nets me:

Android NDK: Found platform level in F:/android-imagemagick/project.properties. Setting APP_PLATFORM to android-8.

Which part of the Android.mk file in the jni folder do I need to change?

Here's my current modified jni/Android.mk file that resolved this:

Magick_Home := F:/Android-ImageMagick/ndk-modules/ImageMagick-6.7.3-0

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE    := android-magick
LOCAL_SRC_FILES := jmagick.c
LOCAL_SRC_FILES += magick_DrawInfo.c
LOCAL_SRC_FILES += magick_ImageInfo.c
LOCAL_SRC_FILES += magick_Magick.c
LOCAL_SRC_FILES += magick_MagickImage.c
LOCAL_SRC_FILES += magick_MagickInfo.c
LOCAL_SRC_FILES += magick_MontageInfo.c
LOCAL_SRC_FILES += magick_PixelPacket.c
LOCAL_SRC_FILES += magick_QuantizeInfo.c \
                   magick_MagickBitmap.c

LOCAL_C_INCLUDES += $(Magick_Home)/include/ImageMagick
LOCAL_C_INCLUDES += $(Magick_Home)
LOCAL_CFLAGS += -L$(Magick_Home)/lib
LOCAL_STATIC_LIBRARIES := MagickCore jpeg coders tiff-static filters
LOCAL_SHARED_LIBRARIES += MagickCore jpeg coders tiff-static filters

#LOCAL_SHARED_LIBRARIES := MagickCore png15 bz2 gomp pthread
LOCAL_LDLIBS += -L$(LOCAL_PATH)/../lib -lz -lfreetype -lpng -llog

include $(BUILD_SHARED_LIBRARY)

include F:/android-imagemagick/lib/freetype/jni/Android.mk
include F:/android-imagemagick/lib/libpng/jni/Android.mk
include F:/android-imagemagick/lib/zlib/jni/Android.mk

$(call import-module,ImageMagick-6.7.3-0)
$(call import-module,jpeg)

The includes are for the freetype, libpng, and zlib modules in the lib folder. I also had to change the LOCAL_MODULE name in the lib/zlib/jni/Android.mk to libz from zlib.
