Of course, it does'nt work on FreeBSD, because our status has a
different structure.
As a quick dirty work-around, I patched it to replace /proc by
/compat/linux/proc and it works. Unfortunately, this is not a good
solution, because this port is no more packageable (this piece of code
is run at the end of the build).
It's why I'm looking for help here: does somebody knows how the
corresponding values of these Vm... can be found in FreeBSD?
