I was just going to mail an updated series for this. I'd definitely like to see this upstream. I amended the first patch to install the notmuch.h header. The second patch from a friend of mine fixes a parallel make issue I ran into when I tested one of your intiial patches. I ran this patch by you ages on #notmuch, not sure why it isn't included, not sure why you didn't included it? The third patch adds a way to configure where to install libraries. On Exherbo x86_64 we install 64 bit libraries to /usr/lib64/ so I need a switch to configure this. Regards, Ingmar
