Okay, so the problem appears to be a straightforward failure to find the 
function in the library.

Probably I would first check that the library is in a standard place: 
'sudo updatedb; locate libjson'.  It could be the library is named 
something else, like libjson-c or something, and for some reason 
configure didn't get the clue to link to the other name.

If the library seems to be in the right place, I would probably try 
running the gcc conftest.c line from the terminal to figure out why it's 
not finding it.

Sometimes if I start to feel crazy I check the headers, etc. to be sure 
that the function that is being looked for didn't get removed from the 
library, but that's rarely the issue.
