[pgsql-jp: 37431] configureに失敗する

[(MPS)村山]

お世話になります。村山と申します。
早速ですが、PostgreSQLのインストールについての質問です。
何故、以下のように、configureで失敗するのでしょうか？

OS：HP-UX　11i　　にて
./configure --enable-multibyte=EUC_JP --without-readline --without-zlib
を実行すると、
以下のエラーを出力します。
checking build system type... hppa2.0w-hp-hpux11.11
checking host system type... hppa2.0w-hp-hpux11.11
checking which template to use... hpux

See `config.log' for more details.
