It's definitely not a requirement on linux, I use clang for C++, not 
Objective C, and certainly not Objective-C libraries.  On my system the 
above command would install 63 additional packages and take 135MB.

I guess GNUstep is to Objective C what QT is C++?

I'm not an Objective C kinda guy, the above statement is probably 
completely wrong :P

Whilst I have your attention, can you package libc++ built against 
libc++abi?  That would be awesome :)
