Building MT with postgresql requires a bit of fiddling. Passing the same flags to mtmapper looks promising but fails quickly on make.

try inserting a

#include <stdlib.h>

in the offending cpp file.

@sofar That worked :) I haven't run it yet, but it built. Thanks a ton!

edit: Don't know if this warrants closing this?
