I'm surprised to see errors after building 0.5.3 BitShares.. I wonder the main branch has new bits and pieces that should be kept within /DevShares. BitShares clean and DevShares dirty?
make[2]: *** [tests/drltc_tests/fc_math/CMakeFiles/multest.dir/multest.cpp.o] Error 1
make[1]: *** [tests/drltc_tests/fc_math/CMakeFiles/multest.dir/all] Error 2
make: *** [all] Error 2
Error above followed from both [cmake -DCMAKE_BUILD_TYPE=Release .] and [git checkout v0.5.3].
Perhaps those tests are not important but seeing any error might put new users off? Also, it would be good to see the BUILD_UBUNTU.md suggest the same as the build instructions on the wiki - or vice versa. I guess for BitShares using -DCMAKE_BUILD_TYPE=Release is better than just cmake .
