the error is actually in ROOT, libRIO does not find someting in the standard library.

one possible source of trouble is mismatched compilation flags, to debug this, please 
use "make cmake" and email me (or post here) the full output. (standard cmake hides 
all compiler information to make it easier to debug such problems).

since this is a prerelease of ROOT 6.32 (which in turn fixes major breakage on MacOS) 
and you built it from sources, can you confirm for me that it actually works, you can 
run "root -l somefile.root", open the tbrowser, look at some plots? this is to 
eliminate the possibility that your ROOR is miscompiled.

hmm... also please run "make cmake -k", let's see is linking of rmlogger also fails.

K.O.
