memsup:get_system_memory_data/0 not working on FreeBSD?

[Daniel Solaz]

this is Erlang/OTP 8.1 compiled from sources on FreeBSD 4.4
as far as I've seen os_mon works fine except for

(erl40016@REDACTED)4> memsup:get_system_memory_data().

memsup:get_memory_data/0 works:

(erl40016@REDACTED)5> memsup:get_memory_data().
{525221888,479645696,{<0.23.0>,284704}}

is this known?
is this a bug? should I report it as such?
