I noticed the new directory structure, so that's not the issue.
I'll try .37 and commenting out stuff (I was using .28 for a long time, 
but I was still using this when the compiling started failing).
One problem with commenting out code is that compilation takes a lot of 
time (especially for dwt) - For some reason rebuild seem to do a full 
compilation even if I have dwt precompiled and use -llDD-dwt, or perhaps 
I'm just a bit stupid :|
