Since version 0.5.0, the Overflow include dir changed from $prefix/include to
$prefix/include/overflow. The reason for that is that it is now possible to set
$prefix to /usr without getting tons of includes into /usr/include (which then
causes problems when you want to install a newer version). This normally
shouldn't have broken the build if it was setup correctly. There is a shell
script called overflow-config (it works the same way as gnome-config) that
should return the right flags to put with Overflow. For example:
'overflow-config libflow --cflags' outputs:

That way, whenever the directories change things keep working.

This problem is quite odd and I haven't figured out why it works on some
machines and not on others. What compiler are you using? For now, you can safely
comment line 247 in /opt/overflow/include/net_types.h and things are still going
to work.
