I think the -rpath option should be used when linking Piper to
libflow.so, so it can be found automatically (of course, you can use
LD_LIBRARY_PATH as Jarl suggested). 

There is now another option: installing Overflow with --prefix=/usr. I
originally strongly recommeded not to usr /usr or /usr/local, but since
0.5.1 it is OK (and recommended). This is why I absolutly needed to move
the includes so they don't end up all in /usr/include (and cause
problems with the next compilation).

By configuring with --prefix=/usr, you get all the executables in
/usr/bin and libflow in /usr/lib, the includes in /usr/include/overflow
and the rest in /usr/share/overflow.
