This is a conflict between Gem.pd_linux 0.92 and Gem 0.90 headers, or 
equivalent. I don't know the exact versions and dates involved, but at 
some date, a function named «GemException::report() const» was removed 
from Gem, for whatever reason, and it causes the GridFlow-Gem adaptör to 
fail to load if you used the Gem headers bundled with GridFlow, or just 
old headers.

Basically, all Gem externals that are outside of the main Gem library have 
to be recompiled once in a while, to match the Gem ABI.

Perhaps Johannes has a few words to say about how this change happened?
