FreeBSD has a sysinfo utility, see "man 8 sysinfo", which can
be obtained with the "sysinfo" package. But as far as I can see,
it's implemented via shell scripts. On Linux systems, sysinfo.h
is a system-level header file.

More precisely: sysinfo.h is part of the GNU C library (glibc)
include files, where sysinfo() is a library function, not an
external program.

See for example:

http://www.informit.com/articles/article.aspx?p=23618&seqNum=15

Also see:

http://man7.org/linux/man-pages/man2/sysinfo.2.html

Let me quote: "This function is Linux-specific, and should not
be used in programs intended to be portable."

Summary: It's a Linuxism. :-)

But maybe you can "fake" the required functionality somehow through
FreeBSD's Linux ABI... There are also ports which seem to install
a sysinfo.h file (search for *.plist containing "sysinfo.h"), for
example devel/libgtop or lang/gnatdroid-sysroot. Maybe that's a
way to get the required files?
