Dear Bas,

Which version of ROOT did you install, especially, which file did you 

The README file says that you should install root_v5.34.05, e.g. from:

However, I just realized that on the Bioconductor production machine 
perceval, which is used to build the xps binary, an old version of root 
is installed, which did escape my attention, see:
So maybe you need to install the old version root_v5.26.00c from:

Alternatively you could download the xps source and build the binary 
yourself. However, this would require that you have Xcode installed on 
your Mac.

Please let me know if this info could solve your problem.

I apologize for the inconvenience, and I will ask the Bioconductor 
maintainers if it would be possible to install root_v5.34.05 although it 
is the production machine.

Best regards,
C.h.r.i.s.t.i.a.n   S.t.r.a.t.o.w.a
V.i.e.n.n.a           A.u.s.t.r.i.a
