o just build libdwarf and dwarfdump one might do:
./configure
make dd
#You may need to be root to do the following copy commands
cp dwarfdump/dwarfdump      /usr/local/bin
cp dwarfdump/dwarfdump.conf /usr/local/lib
#The following is optional, not needed to run dwarfdump
#when doing the default build.
cp libdwarf/libdwarf.a      /usr/local/lib

For a simple build of libdwarf, dwarfdump, and dwarfdump2
and the other tools:
./configure
make
cp dwarfdump2/dwarfdump <somewhere>
#Optionally: cp libdwarf/libdwarf.a <somewhere>

To build all the tools (including dwarfgen and
dwarfexample) use 'make all'. There are known
small compile-time issues with building dwarfgen on
MaxOSX and most don't need to build dwarfgen.
./configure
make all

To also build a shared libdwarf in the process, do:
./configure --enable-shared
make
cp libdwarf/libdwarf.so <somewhere>
cp dwarfdump2/dwarfdump <somewhere>

When ready to create a new distro,
do
./CPTOPUBLIC
./BLDLIBDWARF yyyymmdd
where that could be
./BLDLIBDWARF 20140131
as an example.
