The devel/readline port clashes with the old libreadline in base.
Yes, the library is named "ereadline", but the header files still
collide.

devel/R fails with

  ../../lib/libR.so.1.1: undefined reference to `rl_sort_completion_matches'

when devel/readline is around:

  #if RL_READLINE_VERSION >= 0x0600
      /* if (rl_readline_version >= 0x0600) */
      rl_sort_completion_matches = 0;
  #endif

Not sure what to do about this.  Maybe put devel/readline's headers
into a nonstandard location and patch the ports that actually need
it?

(This is not release critical.)
