there is a port of sar (which is not linux specific BTW I know it
works on SCO for instance, so you may be able to compile the gnu sar
utility):
/net/sysutils/bsdsar

although, I believe there are more elegant way's to collect this info
than via sar on BSD (using iostat systat for example).  The
documentation is very good as well for these utilities.  Regarding the
"free" command, you can get this info via vmstat.  Running it with no
switches will show your the avail memory and free memory.  Again, the
doc for vmstat is very helpful.
