Failure to configure on 10.0

I just got myself an AMD64 computer and have run into some problems. When I try ./configure prior to compiling a program I get the following message " checking build system type... admin/config.guess: unable to guess system type This script, last modified 2003-06-17, has failed to recognize the operating system you are using. It is advised that you download the most up to date version of the config scripts from ftp://ftp.gnu.org/pub/gnu/config/ If the version you run (admin/config.guess) is already up to date, please send the following data and any information you think might be pertinent to in order to provide the needed information to handle your system. config.guess timestamp = 2003-06-17 uname -m = x86_64 uname -r = 2.6.13-15.8-default uname -s = Linux uname -v = #1 Tue Feb 7 11:07:24 UTC 2006 /usr/bin/uname -p = /bin/uname -X = hostinfo = /bin/universe = /usr/bin/arch -k = /bin/arch = x86_64 /usr/bin/oslevel = /usr/convex/getsysinfo = UNAME_MACHINE = x86_64 UNAME_RELEASE = 2.6.13-15.8-default UNAME_SYSTEM = Linux UNAME_VERSION = #1 Tue Feb 7 11:07:24 UTC 2006 configure: error: cannot guess build type; you must specify one " What shall I do to make configure to work?
