When I have this sort of problem, it is because 'make clean' doesn't
always clean up everything. You might want to find and remove all .o and
.so files in your build tree.

If you have a git repo, you can also do 'git clean -f -dx' but make sure
you save anything you might want to keep, such as config.log, if you use
that to track your configure options.

Hope that helps,
