Hmmmmm, now let me try to remember how that worked for me.
I downloded the whole geekgadgets (minus the alpha stuff ;-) ).
There was a file called boot.lha (or something like that).
This has to be unpacked,as it includes all needed for the
final install.
In there is a readme, which also includes a small shell-script.
Edit that to fit your pathes (and you might need to include
the dir into your path).
Now type "sh" in shell,this should bring up a "$" as prompt as
you are now in some kind of unix-shell.
Execute the install-script, and watch the tar.gz-files being
unpacked.
Copy the assigns from the readme (the one in boot.lha), reboot
and you should be ready to compile simple console-apps.
Now you need the OS-includes from the NDK3.9 or a DEV-CD, which
go into include/os-include,and you should be all set.
