Please try again.
Thank you for your response. I tried to build with "ltp-66d67b5.tar.gz", but it failed in configure. Therefore, I tried with older git "ltp-92dfd5b.tar.gz", and it succeeded in RHEL5.5-x86 and RHEL4.8-x86 systems. From "ltp-92dfd5b.tar.gz" to "ltp-66d67b5.tar.gz", new probrem occured. New revisions are released in sequence. Therefore I intend to build with the latest version again.
