Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following "config" scripts:

    /Applications/Postgres.app/Contents/MacOS/bin/gdal-config
    /Applications/Postgres.app/Contents/MacOS/bin/geos-config

Welcome to Notmuch, a system for indexing, searching and tagging your email.

We hope that the process of building and installing notmuch is quick
and smooth so that you can soon be reading and processing your email
more efficiently than ever.

If anything goes wrong in the configure process, you can override any
decisions it makes by manually editing the Makefile.config file that
it creates. Also please do as much as you can to figure out what could
be different on your machine compared to those of the notmuch
developers. Then, please email those details to the Notmuch list
(notmuch@notmuchmail.org) so that we can hopefully make future
versions of notmuch easier for you to use.

We'll now investigate your system to verify that all required
dependencies are available:

Checking for Xapian development files... Yes (1.2.13).
Checking for GMime development files... Yes (gmime-2.4 ).
Checking for Glib development files (>= 2.22)... Yes.
Checking for talloc development files... Yes.
Checking for valgrind development files... No (but that's fine).
Checking if emacs is available... Yes.
Checking which platform we are on... Mac OS X.
Checking for getline... Yes.
Checking for strcasestr... Yes.
Checking for rpath support... No (nothing to worry about).
Checking for -Wl,--as-needed... No (nothing to worry about).
Checking for available C++ compiler warning flags...
        -Wall -Wextra -Wwrite-strings -Wswitch-enum
Checking for available C compiler warning flags...
        -Wall -Wextra -Wwrite-strings -Wswitch-enum -Wmissing-declarations

All required packages were found. You may now run the following
commands to compile and install notmuch:

        make
        sudo make install

==> make install
make install
Use "/usr/bin/make V=1" to see the verbose compile lines.
