It's ok for me. I commited the diff as pkgsrc patch.

I think the dependency is added only if readline is enabled.

if test x$enable_readline = xyes; then
  AC_CHECK_HEADER(readline/readline.h, have_readline_hdr=yes)
  AC_CHECK_LIB(readline, readline, have_readline_lib=yes, , -lcurses)
  AC_CHECK_HEADER(readline/history.h, have_history_hdr=yes)
  AC_CHECK_LIB(readline, add_history, have_history_lib=yes, , -lcurses)
  if test x$have_readline_hdr = xyes -a x$have_readline_lib = xyes; then
    if test x$have_history_hdr = xyes -a x$have_history_lib = xyes; then
      AC_DEFINE([PHYSFS_HAVE_READLINE], 1, [define if we have readline])
      LIBS="-lreadline -lcurses $LIBS"

I'm not sure if it's a Mac OS X specific issue. I can't find where
"-lreadline -lcurses" is added to LIBS in configure, but I'm not an
automake/configure expert.
