I should have been more clear.  Sorry.   The incompatabilities happen at 
linker time, with complaints such as:

exrstdattr: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found 
(required by exrstdattr )
exrstdattr: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found 
(required by /usr/local/mrViewer/lib/libIlmImf-2_2.so.22 )

If I copy the latest libstdc++.so.6 I have on Ubuntu, I get:

exrstdattr: /lib64/libc.so.6: version `GLIBC_2.18' not found (required 
by /usr/local/mrViewer/lib/libstdc++.so.6 )
