>Description:
  Probably multi-byte support of grep has broken with -w option(word match).

  %echo elisp foo lisp | env LANG=C grep -w lisp
  elisp foo lisp
  %echo elisp foo lisp | env LANG=ja_JP.eucJP grep -w lisp
  %echo elisp foo lisp | env LANG=ja_JP.SJIS grep -w lisp
  %echo elisp foo lisp | env LANG=zh_TW.Big5 grep -w lisp
  %echo elisp foo lisp | env LANG=zh_CN.GB2312 grep -w lisp
  %echo elisp foo lisp | env LANG=ko_KR.eucKR grep -w lisp

  For this reason, ports of a lisp category cannot be build.

  % setenv LANG ; cd /usr/ports/lang/sbcl
  % make
  sbcl-0.9.8: Makefile error: category lisp not in list of valid categories.
  *** Error code 1

>How-To-Repeat:
 It is as having written above.

>Fix:
I repealed multi-byte support.
And I can build ports of lisp category.
