Debian appends a version number to the GCC libobjc package.  It supports the 
same features of Objective-C as GCC (i.e. nothing vaguely recent).  It is 
absolutely not the one that you want.  Please complain to the Debian clang 
maintainer that it’s pulling in this dependency, as it’s not the one that he 
wants.

Apple’s libobjc4 has a version number that makes sense, as it corresponds to 
the language version, though Apple then confused everyone by branding the 
version of Objective-C that came after Objective-C 4 as Objective-C 2.0.

GNUstep libobjc (a.k.a. libobjc2) was written to support Objective-C 2.0 
features and be useable with clang.  It supports a superset of the features of 
Apple libobjc4 and runs on most *NIX platforms.

You should use GNUstep libobjc.
