Not really the internal part are sure more complex but the installation steps are far from
being as complex as gnome for example

Hu actually there is nothing to compile except the globals.cpp file
the packages deal with having blitz installed correctly in path that makes sense
I use blitz in several project and I just wanted to have a clean install
the header files go into /usr/include/blitz and /usr/include/random
and there is libblitz.{so,a} in /usr/lib
the only issue I see is what if you want to change config.h (enabling different things in blitz)!
what you can do is copy the file and #define and #undef the preprocessing variables you want by hand
and make sure that your config.h will be seen before the one in /usr/include/blitz.
I added a file blitz.cpp with a dummy C function (wrapped around and extern "C") to liblitz so that people
checking for blitz existence using autoconf just have to add this to their configure.in
AC_CHECK_LIB(blitz,ACCheckBlitz,,[
echo "blitz is not installed"
exit 0
],)
regards
C.
