Sorry if my prior posts were garbled. To clarify:

When exporting src blocks for which there is no execute function for the lang, 
the block will not be executed and the export will proceed.

When evaluating src blocks in other circumstances, e.g. M-x 
org-babel-execute-buffer, the process will terminate when 
org-babel-execute-src-block issues `(error "No org-babel-execute function for 
%s!" lang))'

The latter can be a clue that the name of a lang is misspelled or that 
org-babel-load-languages needs to be customized to provide the execute function.

IMO, nothing needs fixing. The ability to handle OP's original issue is already 
in place.
