esp8266@esp8266-VirtualBox:~$ sudo echo $PATH
/opt/xtensa-lx106-elf/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

$PATH here is expanded in the context of a shell where you type and run the command.
If you want the root shell to expand its own environment, try this: sudo bash -c 'echo $PATH'

Damn, Linux continues to fool me.

Now I understand why SUDO MAKE cannot find XT-XCC.

Thanks jcmvbkbc.

UPDATE : IT'S COMPILING NOW!
Inspired by the tip from jcmvbkbc I switched to the root environment with SUDO-S. XT-XCC is in $PATH, and MAKE in the APP directory compiles, and generates BIN files. I'm over this hurdle now, time to call it quits for today. Thanks for the inspiration in my hour of need.

- Sun Nov 02, 2014 10:46 am #2150 Were you able to successfully burn the compiled code into the module and boot it?
I have tried with the provided iot_demo and AT source, both compiled, both burned but didn't run
flashed the bins at 0x0 and 0x40000 as stated in the docs.

No, I still have to get esptool running on my installation, so cannot help you there.
