Yes, if there is a plugin built against 5.7, or the 6.5-built plugin is 
seeing the 5.7 *.so shared objects, it will complain. I'm not sure that 
you can work around this easily - you would need not to use GDAL at all, 
I'm afraid, to be sure. My practice would most likely be to have two 
different users with local installs of everything and local LD path 
variables. The plugin "architecture" is designed for a single environment, 
one GDAL and one GRASS only in my experience.

Best wishes,

Roger
