by gameroot i mean your assets(models, maps, scripts, textures, shaders etc.) dir, these files are included in the latest stable build:
svn co -r 1526 http://zeq2.com/SVN/Build/ zeq2lite
You said that you want a amd64 build, but there is none, so you have to build one from source:
svn co -r 1526 http://zeq2.com/SVN/Source/ zeq2litesource
after an successful build copy the new amd64 binary and its libraries to your previously downloaded stable build

If you built the game in the folder zeq2litesource, how comes you gameroot is zeq/zeq2lite?
Actually, I think I am getting confused on what you mean by GAMEROOT at this point...
if you extract the content of the package the binary is called: soulride.
maybe its a different version?
Make sure that you run it from the gameroot eg: cd $GAMEROOT && ./ZEQ2.$ARCH
your folder should look like this:
