That's because the Ubuntu packages for libobjc (which is really GCC libobjc 3) don't install the headers anywhere sensible.  They are installed, but in a stupid place.

The best way of compiling Objective-C code under Linux is to use GNUstep Make (should be in packages for Ubuntu), which handles all of this for you.

If you want to use the non-fragile ABI and declared properties then you will need to either use the GNUstep Objective-C runtime or link against a recent version of the GNUstep-base (Foundation) library.
