Error trying to build tesseract-android-tools sample

[GoogleCodeExporter]

What steps will reproduce the problem?
1.I compiled tesseract-3.01
2.I compiled leptonica-1.68 and libjpeg
3.Add the right 3 paths in Android.mk of the sample 
tesseract-android-tools-1.00.

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
