It seems related to a mutli-processor build, if build with -j12 it produces this, or another similar error. When building with -j1 it works, when created from a clean unzip. And once a build has failed with -j2+ it can be correctly build with even -j1. Or I don't know which part to clean correctly.
I also realized that the 00.02.06 for TRB-1 has disappeared from the download page or where did I get this package from?
$ md5sum ../TRB1_R_GPL_00.02.06.tar.gz
