Here is the build process that worked for me

sudo apt-get install pinentry-curses

add pinentry-program /usr/bin/pinentry-curses to ~/.gnupg/gpg-agent.conf

#cd

#wget ftp://ftp.gnupg.org/gcrypt/gnupg/gnupg-2.1.0.tar.bz2

#wget ftp://ftp.gnupg.org/gcrypt/gnupg/gnupg-2.1.0.tar.bz2.sig

#gpg --verify gnupg-2.1.0.tar.bz2

#tar -xvf gnupg-2.1.0.tar.bz2

#cd gnupg-2.1.0

#make -f build-aux/speedo.mk native

#export LD_LIBRARY_PATH="/home/[user]/gnupg-2.1.0/PLAY/inst/lib"

#cd PLAY/inst/bin

#./gpg2
