can't build tesseract-android-tools sample

[GoogleCodeExporter]

What steps will reproduce the problem?
1. I'am trying to run the sample tesseract-android-tools-1.00, I installed 
leptonica-1.68,tesseract-3.01 and jpeg-8c and android-ndk-r7, all these steps 
gone without problems.
2. I defind the right paths for TESSERACT_PATH, LIBJPEG_PATH, LEPTONICA_PATH in 
jni/Android.mk.
3. when I tried to build the sample tesseract-android-tools-1.00 using 
./ndk-build in ndk root I got the provided error.

What is the expected output? What do you see instead?
I run ./ndk-build in android-ndk-r7 folder but I get this result:

./ndk-build
