GnuGP and libgcrypt development version build successfully on my
32-bit ARMv7l.

Good, you have the libgcrypt development version installed.

How do you install the libgcrypt on your system?

If it's /usr/local/lib, you would need LD_LIBRARY_PATH setting.

    $ export LD_LIBRARY_PATH=/usr/local/lib

For me, with LD_LIBRARY_PATH, it goes:

    $ gpg2 --version
    gpg (GnuPG) 2.1.11-beta67
    libgcrypt 1.7.0-beta298
    NOTE: THIS IS A DEVELOPMENT VERSION!
    It is only intended for test purposes and should NOT be
    used in a production environment or with production keys!
