Hey, Sebastien.  You can determine the loaded version of a library from
within emacs with the follow command:

M-x locate-library notmuch

It's also good to know how many notmuch instances are installed on your
system.  For instance, I have a system-wide installation, a "personal"
installation, the build currently in the source tree, etc.  Depending on
the options I supply to emacs at startup, I could run a variety of
versions.

jamie.
