Your project is very interesting - please keep me updated on your findings!

I've never compiled olsrd statically - and I can't seem to make it link 
here... The way I see it a -static added to the linking line in the 
Makefile should do it since both libpthread.a and libm.a exist on this 
system... But the linking fails...
I'll have to get back to you on this later.

Yes - I will include it in the next release as well.
