Hi,

I assume you ran ndk-build after running mocl?

Yes, the steps I ran were 
export NDK_PROJECT_PATH=~/mocl-example-lisp-contacts-android/LispContacts
mocl --android LispContacts app.lisp 
~/android-ndk-r9c/ndk-build
#The output is 
Android NDK: WARNING:/Users/jaimef/mocl-example-lisp-contacts-android/LispContacts/jni/Android.mk:program-jni: non-system libraries in linker flags: -l/Users/jaimef/mocl-example-lisp-contacts-android/LispContacts/jni/mocl/libmocl.a    
Android NDK:     This is likely to result in incorrect builds. Try using LOCAL_STATIC_LIBRARIES

Normally there should not be any NDK warnings.

Instead of exporting NDK_PROJECT_PATH, please try going to the jni subdirectory (e.g. ~/mocl-example-lisp-contacts-android/LispContacts/jni) and running ndk-build from there.

By the way, there is a "build the example" walk-through at http://markwatson.com/blog/2013-06/interesting-product-mocl.html if you run into any other issues.

Update: these instructions are better

I was following the walkthrough from Mark Watson.
Will read the other one.

Thanks, the step of "cd jni && ndk-build" fixed it.
