CentOS5.2でErlang R12B-4をbuildしようとしてエラーになった

このエラーで検索したところ、[erlang-questions] Problem compiling under CentOS 5から始まるスレッドの終わりの記事が参考になりそうだ。Makefileの不備らしい。
パッチが出ている。要するにkeyutilsとselinuxのライブラリをリンクし忘れてましたってことです。エラーの冒頭に出てくるkeyctl_read_allocは /usr/include/keyutils.h で定義されてましたから、納得です。

実際に lib/ssl/c_src/Makefile.in を編集して ./configure ; make したら通りました。

ところで、ライブラリを明示的に指定しないでＯＫだったケースというのは、どう理解したらいいものやら。リンクしていたライブラリが、その機能を参照してなかったということなのだろうか？
(2009/1/19追記
トラックバックをいただいていたのだが、R12B-5でも同じ問題が残っていることを確認できた。）
(2009/5/26追記 R13Bでも同様の方法でbuildできました)
