...but you must have made some changes.  Following the instructions, I'm getting build errors on compiling leveldb...

g++ -c -mthreads -O2 -w -Wall -Wextra -Wformat -Wformat-security -Wno-unused-parameter -g -DWIN32 -D_WINDOWS -DBOOST_THREAD_USE_LIB -DB

alert.cpp:6:53: fatal error: boost/algorithm/string/classification.hpp: No such file or directory
compilation terminated.
mingw32-make: *** [obj/alert.o] Error 1


...I'm not sure why but it can't find a boost file which is definitely there....
