[tex-live] 2015 pretest

[jfbu]

Hi,

I wanted to try out the TL2015 pretest, 

but I don't understand the situation with binaries, for example in 

/Users/???/Downloads/TL2015/bin/x86_64-darwin

I have

ttys000:Downloads (09:36)$ ls -l TL2015/bin/x86_64-darwin/xetex
-rwx------  1 ??? ????  19431216 22 mai  2014 TL2015/bin/x86_64-darwin/xetex

which is the TL2014 (not 2015) binary

I proceeded via

rsync -a  --delete --exclude="mactex*" -- ctan.ijs.si::mirror/tlpretest/ ~/Downloads/tlpretest/

then I ran tl-install and got the things installed in my

~/Downloads/TL2015

I manually manipulated the /Library/TeX/Distributions/ (this is on Mac OS X) 
to add a TeXLive-pre2015.texdist collection of symbolic links and it is
all perfectly fine.

However I got surprised with a test file for xetex + pstricks not
working properly
and in the
end realized that there was no problems with my symbolic links
but that the installed binaries were the ones of TL2014, not TL2015.

Is this a problem of my chosen TL2105 pretest mirror ?

best

Jean-Francois
