The summary line should be "gnu: Add envstore."

You misspelled "envstore.scm", but it would be better to find an
existing file in gnu/package/*.scm that would be appropriate for this.

When adding a new *.scm file, it needs to contain a copyright notice and
header at the top, as with our other source files.

How about using

  https://finalrewind.org/projects/envstore/envstore-2.1.tar.bz2

instead?  That's the tarball linked from the project's home page, and
unlike the github tarball, it's digitally signed.

Instead of replacing the 'build' phase, it would be better to add this
to the 'arguments':

  #:make-flags (list "CC=gcc")

See 'dvtm' in dvtm.scm for an example.

These are incorrect settings for PREFIX and DESTDIR.  In general, PREFIX
tells where the installed files will be located when the program is run,
and DESTDIR names a temporary staging directory where "make install"
will put the files, on the assumption that they will later be moved to
PREFIX before they are run.

So, PREFIX should be set to (assoc-ref outputs "out"), and DESTDIR
should be left alone.

Also, as with the 'build' phase, it would be better to simply add these
to make-flags, like this:

  #:make-flags (list "CC=gcc"
                     (string-append "PREFIX=" (assoc-ref %outputs "out")))

Can you send an updated patch?

     Thanks,
