Thank you nobu. Upgrade required version of autoconf prevent smooth install on some platforms still used widely (Lion, CentOS 6.3). I'll merge Hessob's patch by hand. ---------------------------------------- Backport #8020: make-snapshot fails since r39221 https://bugs.ruby-lang.org/issues/8020#change-38932 Author: phasis68 (Heesob Park) Status: Assigned Priority: Normal Assignee: nagachika (Tomoyuki Chikanaga) Category: Target version: $ ruby tool/make-snapshot /tmp/snapshopt trunk@39221 Exporting trunk@39221 Exported revision 39221. take a breath, and go ahead creating configure...configure:1507: error: possibly undefined macro: _m4_text_wrap_word If this token and others are legitimate, please use m4_pattern_allow.
