CVS and compilation

I download all the code from CVS procedure, also I downloaded 'autoconf'
'automake' and 'libtool' from GNU.
I installed 'autoconf' 'automake' and 'libtool'.
And when I run the './configure' in '/usr/local/libwww', this is the error.

Ltconfigure: unrecognized option '-build=i386-unknown-freebsd3.2'

My system is FreeBSD 3.2 .

Could somebody helpme ?
Thanks
