Instructions to build Solidity on Ubuntu 16.04

Minimal dependencies for Solidity on Ubuntu 16.04, removed those for older Ubuntu versions for now (they were a bit confusing).
Removed --all and added -DETHASHCL=0 to ethbuild.sh when building Solidity only.

-Ubuntu
-------
+Ubuntu 16.04
+------------
 
-Below are the build instructions for the latest versions of Ubuntu. The best
-supported platform as of December 2014 is Ubuntu 14.04, 64 bit, with at least 2
-GB RAM. All our tests are done with this version. Community contributions for
-other versions are welcome!
+Below are the instructions to install the minimal dependencies required
+to compile Solidity on Ubuntu 16.04 (Xenial Xerus).
 
-Install dependencies:
-
-Before you can build the source, you need several tools and dependencies for the application to get started.
-
-First, update your repositories. Not all packages are provided in the main
-Ubuntu repository, those you'll get from the Ethereum PPA and the LLVM archive.
+One of the dependencies (Crypto++ Library, with version >= 5.6.2) can be
+installed either by adding the Ethereum PPA (Option 1) or by backporting
+``libcrypto++`` from Ubuntu Development to Ubuntu Xenial
 
 .. note::
 
-    Ubuntu 14.04 users, you'll need the latest version of cmake. For this, use:
-    `sudo apt-add-repository ppa:george-edison55/cmake-3.x`
-
-Now add all the rest:
+    These dependencies are not enough to compile the GUIs (Alethzero and Mix)
 
 .. code-block:: bash
 
-    sudo apt-get -y update
-    sudo apt-get -y install language-pack-en-base
-    sudo dpkg-reconfigure locales
-    sudo apt-get -y install software-properties-common
+    sudo apt-get -y install build-essential git cmake libgmp-dev libboost-all-dev \
+        libjsoncpp-dev libleveldb-dev libcurl4-openssl-dev libminiupnpc-dev \
+        libjsonrpccpp-dev libmicrohttpd-dev
+    
+    # (Option 1) For those willing to add the Ethereum PPA:
     sudo add-apt-repository -y ppa:ethereum/ethereum
     sudo add-apt-repository -y ppa:ethereum/ethereum-dev
     sudo apt-get -y update
     sudo apt-get -y upgrade
-
-For Ubuntu 15.04 (Vivid Vervet) or older, use the following command to add the develop packages:
-
-.. code-block:: bash
-
-    sudo apt-get -y install build-essential git cmake libboost-all-dev libgmp-dev libleveldb-dev libminiupnpc-dev libreadline-dev libncurses5-dev libcurl4-openssl-dev libcryptopp-dev libjson-rpc-cpp-dev libmicrohttpd-dev libjsoncpp-dev libedit-dev libz-dev
-
-For Ubuntu 15.10 (Wily Werewolf) or newer, use the following command instead:
-
-.. code-block:: bash
-
-    sudo apt-get -y install build-essential git cmake libboost-all-dev libgmp-dev libleveldb-dev libminiupnpc-dev libreadline-dev libncurses5-dev libcurl4-openssl-dev libcryptopp-dev libjsonrpccpp-dev libmicrohttpd-dev libjsoncpp-dev libedit-dev libz-dev
-
-The reason for the change is that ``libjsonrpccpp-dev`` is available in the universe repository for newer versions of Ubuntu.
+    sudo apt-get -y install libcryptopp-dev
+    
+    ## (Option 2) For those willing to backport libcrypto++:
+    #sudo apt-get -y install ubuntu-dev-tools
+    #sudo pbuilder create
+    #mkdir ubuntu
+    #cd ubuntu
+    #backportpackage --workdir=. --build --dont-sign libcrypto++
+    #sudo dpkg -i buildresult/libcrypto++6_*.deb buildresult/libcrypto++-dev_*.deb
+    #cd ..
 
 Building
 --------
 
-Run this if you plan on installing Solidity only, ignore errors at the end as
-they relate only to Alethzero and Mix
+Run this if you plan on installing Solidity only:

     cd webthree-umbrella
