Make sure that you run it from the gameroot eg: cd $GAMEROOT && ./ZEQ2.$ARCH
your folder should look like this:
Game: Virtual Jay Peak
I checked out and built with your command from the start.
After copying the files you suggested, crashlog.txt says it is looking for default.cfg in some different folders.
Still, find / -name default.cfg only gives a result for 0ad and one for vlc.

because you linked the 64Bit build, remove your link and try the solution from above.
use the svn checkout command from above(see description), it will download the current stable(i386) build(~700 MB)
checkout the stable engine code, build and copy $SOURCE/Build/Release-linux-$ARCH/ZEQ2.$ARCH to your gameroot ; copy $SOURCE/Build/Release-linux-$ARCH/Base/*.so to $GAMEROOT/ZEQ2
