I have tried to use this package, but because I am using fink to
install packages the mdbtools binary they are not accessible by the
function from within R.  I checked this by just trying to call it with
the system function and R returned /bin/sh not found.  I can access
the binary from the terminal, so the /sw/bin directory where mdbtools
is located is in my PATH- at least at a terminal.
thanks for the help,

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
