Hi Mikeal,

Thanks for replying so fast.

Excerpts from Mikael Pettersson's message of 2010-09-22 23:17:18 +0200:

Linux maemo-desktop 2.6.27-16-generic #1 SMP Tue Dec 1 17:56:54 UTC 2009 arm GNU/Linux

On the Nokia N900 itself (on the running device, NOT the SDK), I get:
Nokia-N900:~# uname -a
Linux Nokia-N900 2.6.28.10power40 #1 PREEMPT Tue Aug 10 09:30:52 EEST 2010 armv7l unknown

Ah, I see why you don’t have arm/armel in there now.

I have no idea. Maybe the best way to go is to include patches in the maemo
package of erlang for this issue?

Best regards,
