libobjc2 on android

[Germán Arias]

Trying to build libobjc2 on android, with Ivan Vučica instructions, but
using a recent libobjc2, sdk and ndk, I get this error and googling
don't help me:

The path
"/home/german/Instalados/android-toolchains/gs-install/libs/armeabi",
don't exist. But I'm trying to install it at
"/home/german/Instalados/android-toolchains/gs-install/".

Any suggestion? Thanks
