A clean git clone of 6-00-00, using ./configure --disable-fink did not change the results.
I tried installing the new root6 port from MacPorts (which is 6.00.00), and actually it installed seemingly without errors, but when I try to run it, that’s when I get a seg fault which looks similar to the seg fault from when I tried to ./configure && make myself:
*** Break *** segmentation violation

I will email the maintainers listed for this MacPorts port. Perhaps they have some more information about OSX problems.
