It's THE place.

Well, actually it is better to connect the LEDs
via a resistor to Vcc and pull the I/Os to low.

     PORTE &= ~((1<<2) | (1<<3)| (1<<4));

But as you said, it is working without Nut/OS.

No, nothing special is required and your make output
looks perfect. Here's something similar:

Something I can think of is the possibly missing
32 kHz clock crystal on your board. But, AFAIK, this
would not hurt in your simple application, which doesn't
use any kind of Nut/OS timer functions (NutSleep or event
timeouts).

Does your hardware got an external RAM? If not, you may
try the settings in
   RTOS Kernel -> Memory Management
after loading stk501.conf with the Configurator.
