Inspiring is the word I feel always best sums up these Workshop  
experiences.

OK, you actually did double work there. If you downloaded the binaries  
and put them in the proper place(s), and added those places to your  
environment, you should already have a working installation of  
Radiance. You ALSO downloaded the source code and did this:

Here, you are actually trying to compile the source code -- in  
essence, making your own copies of the binaries you already  
downloaded. THe reason this didn't work (errors below) is because you  
don't have a couple of the necessary utilities needed to compile  
source. I recommend you DO learn to compile from source, since it's  
fairly easy on the Mac and this gives you access to the latest- 
greatest features of Radiance, some of which were demoed at the  
Workshop. So, read on...

OK, see the error "make: not found"? This is telling you that the make  
program, which is essential to the entire compilation/installation  
process, is not installed on your computer. What you need to do is  
download and install the developer tools from Apple's website. It's  
called XCode, and it's free, just a hefty download. Head here and grab  
it:

http://developer.apple.com/TOOLS/Xcode/

Once that's installed (and you may need to register on the Apple  
developer website before you can download it, I can't remember), you  
should make sure you have the latest HEAD release along with the  
support files and that they've been unpacked to one "ray" directory  
structure. The instructions and download links for these two files are  
located here:

http://www.radiance-online.org/software/

Scroll down to the section called "Download newer CVS snapshots from  
this server", and grab radiance-HEAD.tgz, and rad3R9supp.tar.gz. Save  
them in the same directory, and unpack them according to the  
instructions on that page. Then change to that ray folder, and type  
"sudo ./makeall install", give the admin password, and you're off to  
the races. This process will compile the latest source and install  
everything to the correct locations, overwriting the older binaries  
you already put in there.

Next step is to --

(Mark Stock just posted the next step (the path stuff); I love this  
list.)

BTW, I usually put the environment variables in my .profile, but the  
default shell on OS X is BASH, so Mark's suggestion will work fine  
too. As Mark said, post any other errors or issues here and we'll get  
you going!
