<SNIP>

The output of your 'getenv ("CC")' is ok. It's set by the startup script of 
Octave.app and is not visible to any other program of your Mac. Now I expect 
that your gcc 4.3.0 does not do the right thing. You should have installed 
Apple's version of GCC in /usr/bin that comes with the XCode tools. Now, how 
can you do that?

a) Find out where /usr/local/bin was added to your system's $PATH environment 
variable and remove it just for the installation of odepkg. After that you can 
add it again. This makes sure that no other program in your /usr/local/bin is 
found.

Close Terminal.app from your Dock and then open a new Terminal.app window, then 
type

  which gcc
  which g++

and check for programs /usr/bin/gcc and /usr/bin/g++. Startup Octave.app and 
try to install the package once again. Finally you can add your /usr/local/bin 
directory to your $PATH once again.

b) rename /usr/local just for the installation of odepkg, eg. rename /usr/local 
into /usr/__local. Then continue with the same steps than in a) by closing 
Terminal.app in the Dock and by checking for gcc and g++.

Best regards,
