Thanks Michal;

I replaced my current main.mk4 with the one you have given below.

I get now a new error:

        No such file or directory

Please see partial listing below (I put the index.log file
also in this folder http://12000.org/tmp/123115/

-------------------------------------------------

May be this is all due to the "DVI error: undefined font number 35"?

May be some thing did not get written to the dvi file due to the
above, and things get messed up?

I am not doing anything different in this file from all my
other builds. Same makefile, same .cfg same main.mk4 (the one
you have below, worked fine on another build, no errors).

Only difference, this file generate this DVI error.

I did clean build. Still get this error.

If you have any suggestions what I can try, will be happy to.
Meanwhile, I'll try to see what this DVI error mean and where
it is coming from as it might be the cause of all this.
