Ok,this looks reasonable.

This is strange, I do not have any conflicts that need to be resolved by 
hand.. What version of ecos you are using? The latest CVS snapshot? Your 
install path of ecos looks like you are using ecos-1.3.1 release, are you?

My experience was, that upgrading, to the latest cvs version solves a lot 
of problems..

Cheers,
Chris
