Hi,

I am off my mac laptop for some hours, and can not test further
until later today. I hope I have not been sending everyone offtrack.

To recapitulate, yesterday I had

1) the pretest from yesterday morning

2) fresh compiled binaries (for mac os x) from the tldevsrc svn trunk. 
I moved all binaries after generation to the bin/ of my TL2015 pretest

3) I then regenerated all formats and got no error message
(I did not check the log, perhaps there were some silent errors)

Today I had

1) the pretest from today morning

2) which includes the binaries for darwin 64 bits

I also tried to recompile the binaries but this changed nothing

I *think* I also tried (but that was 2 hours ago and had lunch
in between) with the yesterday (home compiled) xetex binary together
with the today TL2015, and I got the same Duplicated Pattern errors

This made me think indeed something external to xetex had changed
in between

best
