Because it's genrbox ...

Learn how to use system tools to find out which files have been  
installed
by a package. The program dpkg might be your friend here (I haven't used
Debian/Ubuntu/Linux in a while). The official Debian packages differ  
from
the standard distribution in some minor ways. Plus the tutorials you are
following are outdated in respect to the current version. If you are  
not familiar
with your operating system you will have a hard time understanding  
what's
going on.

As a kick-start help here is the list of files installed by the package:

http://packages.debian.org/lenny/i386/radiance/filelist

 From the above list it's these files you should read:

/usr/share/doc/radiance/NEWS.Debian.gz
/usr/share/doc/radiance/README.Debian
/usr/share/doc/radiance/README.gz
/usr/share/doc/radiance/changelog.Debian.gz
/usr/share/doc/radiance/copyright

The last line is telling: the shell can't find the command called  
'rgenbox' - in this case
because it doesn't exist.

If you have the 'locate' command installed you can search for the  
file on your system
(using a database) or use

find / -name rgenbox

to search the whole system for it (might take a while).

This app has nothing to do with Radiance but it has the same name and
it was in Debian first. So the Radiance 'genbox' command had to be  
renamed
which causes all your troubles right now.
