World: r4wp

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Warning: Your Xcode (4.5.1) is outdated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

Mwah, not really, compared to the rest. Perhaps the site is slow

If you look in /usr/local/lib do you see new *.a files?

a couple GB taken so far, it seems.

from the HD

Done, it seems.

So now I should be able to run your demo?

GTK-browser isn't executable. Should I make it and run from terminal 
or what?

513 ~/Downloads$ chmod +x GTK-browser 
514 ~/Downloads$ ./GTK-browser 
dyld: Library not loaded: /usr/lib/libgthread-2.0.dylib
  Referenced from: /Users/john/Downloads/./GTK-browser
  Reason: no suitable image found.  Did find:

 /usr/local/lib/libgthread-2.0.dylib: mach-o, but wrong architecture
Trace/BPT trap: 5

Doesn't seem to run. :/

Yes, that way you also get stdout output from the demos
