[linux-users:83956] Acrobat Reader日本語フォントインストールで「warning:unportableBRE」エラー

[Hiroshi Nakamura <hnakamur _at_ xxxxxxxxxxxxxxxxx>]

中村と申します。

Red Hat Linux 7JにAcrobat Reader日本語フォントパックをインストール
したのですが、「warning: unportable BRE」とのエラーが出ました。
Acrobat Readerに日本語文書を読み込んで見たところ、ちゃんと表示された
ので、動作自身は正常と思われます。
このエラーがどういうものか教えていただけませんでしょうか。
