I'm not following closely, but seeing paths to programs hard coded in
the source never seems like a good idea; invariably someone will have
the program in an unanticipated location.  I'm using pkgsrc on OS X,
and my gpg is at /opt/pkg/bin/gpg.  How about a Notmuch configuration
file item specifying the location of the program?  Or if not that, how
about a configuration option at build time to specify the location of
gpg that then gets hard coded in the source?  Or if not that, how about
an environment variable that will specify the location of the program
(e.g. like OpenSSH's SSH_ASKPASS environment variable)?
