Building & Installing GMP 5.0.2

curl -O ftp://ftp.gmplib.org/pub/gmp-5.0.2/gmp-5.0.2.tar.bz2
tar xjf gmp-5.0.2.tar.bz2
pushd gmp-5.0.2
CC=gcc-4.2 CXX=g++4.2 ./configure --prefix=/usr/local
make
sudo make install
popd

Building & Installing Libnettle 2.4

curl -O http://www.lysator.liu.se/~nisse/archive/nettle-2.4.tar.gz
tar xzf nettle-2.4.tar.gz
pushd nettle-2.4
CFLAGS="-m64" ./configure --prefix=/usr/local --disable-assembler
make
sudo make install
popd

Building & Installing GnuTLS 2.12.12

curl -O http://ftp.gnu.org/gnu/gnutls/gnutls-2.12.12.tar.bz2
tar xjf gnutls-2.12.12.tar.bz2
pushd gnutls-2.12.12
CFLAGS="-m64" CXXFLAGS="-m64" ./configure --prefix=/usr/local --without-p11-kit
make
sudo make install
popd

I can't get the latest GnuTLS to compile, but configure succeeds if I take some extra steps. Without extra steps, the configure script will fail saying it can't find Libnettle 2.7 despite Nettle compiling fine. I'm trying to build GnuTLS-3.2.1 with GMP-5.1.2 and Nettle-2.7.1 (current latest release of all 3) on OS X 10.7.5

To get around this, you must do two things, one you must set your pkg-config search path to include /usr/local/lib, which you can do with
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/

Once you've done that, if you do the following configure, it will generate makefiles successfully, but can't compile:

CFLAGS="-m64 -pipe -O2 -march=core2" CXXFLAGS="${CFLAGS}" CPPFLAGS="-I/usr/local/include" LDFLAGS="-L/usr/local/lib" ./configure --prefix=/usr/local --without-p11-kit

You end up with the following error:

First, use curl to download the latest wget source:
curl -O http://ftp.gnu.org/gnu/wget/wget-1.13.4.tar.gz

Next we use tar to uncompress the files you just downloaded:
tar -xzf wget-1.13.4.tar.gz

Use cd to change to the directory:
cd wget-1.13.4

Configure with the appropriate –with-ssl flag to prevent a “GNUTLS not available” error:
./configure --with-ssl=openssl

Build the source:
make

Install wget, it ends up in /usr/local/bin/:
sudo make install

Confirm everything worked by running wget:
wget --help

Clean up by removing wget source files when finished:
cd .. && rm -rf wget*

This worked for me.

Why does setting --with-ssl prevent the error? Does it just remove the GNUTLS dependency?

./configure --with-ssl=openssl

Apple OpenSSL implementation already has TSL library.

I run into an error when try to make nettle-2.4 on my MacBook with OS 10.11.5:

In file included from /usr/local/include/gmp.h:50:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/cstddef:46:9: error: no member named

using ::ptrdiff_t;
      ~~^
1 error generated.

I could compile the previous library (GMP 5.0.2) but I had to install gcc-4.2 through brew, the hint from @jaycode (from 12 Jun 2012) didn't help, there was no more 4.2 on my system, I guess this is too old.
What could I do? I don't understand this error.
Or is there another way to get gnutls on Mac OS 10.11.5?
Thanks

EDIT 2016-07-04: never mind, I let go my plan of compiling inadyn on Mac, where I need gnutls. There are too many other issues anyway.

On mac, you have to change the command: CC=gcc-4.2 CXX=g++4.2 ./configure --prefix=/usr/local
to CC=gcc CXX=g++ ./configure --prefix=/usr/local

With macos 10.12.6, I could install GMP, but not Nettle. After running configure and make, I ran make check. The result was:
88 of 89 tests failed

For one thing, it complained that libhogweed.4.dylib could not be found. I tried to attach the history of my installation attempt (starting with curl), and the output of make check to this post as a file, but every time I tried I got an upload error ("We don't support that file type"), even though I tried txt, zip, and pdf versions of the file. So I created a GH repo where you can view the file, here:
