World: r4wp

:)

Well, can't it just use one dir somewhere, like in Applications as 
all the other software do?

Nope, they're ports from Unix, which is quite inflexible about its 
software conventions

ok

OS X wants to be a Unix, so there you go

Downloading and Installing Homebrew...

And then it's counting objects... 113450, done

Git is doing that, I think

I have a hard time figuring out, what Red is. Is there a simple overview 
somewhere?

The apps you see in your Applications use all sorts of Unix infrastructure 
underneath, such as the cURL library, Ruby language and Git tool 
you just found

Think of Red as REBOL that can be compiled. The main docs are for 
Red/System at this point. 

http://static.red-lang.org/red-system-specs.html#section-19.2

Red programs are like the Mac Applications: they don't have to be 
installed and don't care where they run

However, my bindings, like Mac Applications, use infrastructure that 
is included in the ancient Unix parts of the system. So a clash appears, 
when that infrastructure is not installed yet

Seems like I got brew installed, and it sais:

You should run `brew doctor' *before* you install anything.

Interesting

Doing that gives me 7 warnings.

Anything serious?

Warning: Some directories in /usr/local/share/man aren't writable.
Warning: You have leftover files from an older version of Xcode.
Warning: Unbrewed dylibs were found in /usr/local/lib.
Warning: Unbrewed .la files were found in /usr/local/lib.

Warning: Unbrewed .pc files were found in /usr/local/lib/pkgconfig.
Warning: Unbrewed static libraries were found in /usr/local/lib.
Warning: Your Xcode (4.5.1) is outdated
:)

I have no idea, if it's serious.

at the bottom: Please install Xcode 4.6.2.

Doesn't sound serious, except Xcode

hm, well, maybe that's as fra I get now.

*far*

So Red/System is like a base for Red?

Like C is the base for World, yes

ok

And how far is it developed?

Enough to write Red in it :-)

ok, and how far is Red?

So if I would try install the gtk+ using brew, do I write:
brew install gtk+
?

As I said above, best to run GTK-browser to get a feel for the state 
of Red

yes, and I needed gtk+ for that, right? And I needed brew to get 
gtk+.

Yes, so?

Not sure if the name is exactly gtk+. Was that the name of the formula?

So I'm asking, if I know should write
	brew install gtk+

or what? I suggest that, because I see something similar on the brew 
page:
http://mxcl.github.io/homebrew/
, where they do a
	brew install wget

gtk+.br

Yes, you need to fill in the name of the formula

I try. :)

Then the command should be correct. But you should upgrade Xcode 
first

It's doing something.

nah, I try. :)

You get to keep the pieces if you break it
