Install GnuPG by running the following commands:
./configure --prefix=/usr --libexecdir=/usr/lib &&
make &&
make install &&
chmod 4755 /usr/bin/gpg
--libexecdir=/usr/lib: This command creates a gnupg directory in /usr/lib instead of /usr/libexec.
chmod 4755 /usr/bin/gpg: We install gpg setuid root to avoid swapping out of sensitive data.
The GnuPG package contains gpg, gpgsplit and gpgv.
