[Bro] Logging plugin won't configure

[Aaron Gee-Clough]

All,

I'm attempting to build a logging plugin, and hitting a bit of a brick
wall. I have what I think is a reasonable framework, based on the
elasticsearch logging plugin, but when I go to configure it, I get :

g-clef at yog-sothoth:~/workspace/Bro/C++/KafkaLogger$ ./configure

This looks like a regex error in the bro code, rather than in my code,
but I'm not sure what that code is trying to do. Any ideas?

Thanks.
