Right, it looks like a libphysfs-related problem, which has just been
added as a dependency for this release.

I can't reproduce the problem (no kFreeBSD box around yet), but it is
failing at PHYSFS_init(), which looking at libphysfs's code, does some
really weird stuff trying to guess the base directory. But other than
that, there is nothing special about that function: it is either called
with argv[0] or NULL as the only parameter. Other libphysfs-based games
such as Warzone2100 call it exactly like Neverball does. Do you have
similar problems with Warzone2100?

A few days ago I committed a patch to the pkg-games SVN repository
(already applied upstream) that might also be helpful to find out where
exactly in the initialization it is failing.

(This seems to be related to #544835, so fixing this bug will probably
help to fix the FTBFS problems, which seem a bit random at the moment.
Neverball 1.5.2 has only been succesfully (auto) built on armel, i386,
ia64, and mips, yet it builds just fine on my amd64 and powerpc
cowbuilders.)
