16.04 - gnupg-2.2.10 gpg: Fatal: libgcrypt is too old (need 1.7.0, have 1.6.5)

I am trying to install gnupg from source code using the following method:

step 1:

I cd to the uncompressed gunpg-2.2.10

cd Downloads/gnupg-2.2.10

step 2:

I run command :

./configure

step 3:

I run command

make

also I installed the libgcrypt as follow before the previous steps as follow:

step 1:

I cd to the libgcrypt uncompressed folder

step 2:

I run

sudo ./configure

step 3:

I run :

sudo make

step 4:

I run

sudo make install

but every time I go to the folder gnupg-2.2.10/g10 and run

./gpg

I get

 gpg: Fatal: libgcrypt is too old (need 1.7.0, have 1.6.5)

now here is the output of ls /usr/local/lib

libassuan.la        libgcrypt.so.20         libksba.la         libnpth.so.0
libassuan.so        libgcrypt.so.20.2.3     libksba.so         libnpth.so.0.1.2

libgcrypt.so        libgpg-error.so.0.24.3  libnpth.so
