general ports problem

[t-u-t]

hi,
i have a quick question and don't know what this problem is related to.

i am getting an error on *every* port i try to build -- Script "configure"
failed unexpectedly. etc,etc, please check log.

searching the net i am finding pages on particular ports (not same as mine
yet) -- but baffled as to why every port giving this error.

I have no clue what is in these log files and was wondering whether the
"unknown' entries is normal at "/bin/arch=" below.

this below is the topmost part of config.log and just noticed the parts with
win32 and don't know what that means.

the very last line in the log file reads configure. exit 77.

========================

It was created by configure, which was
generated by GNU Autoconf 2.61.  Invocation command line was

  $ ./configure --with-w32-path=/usr/local/lib/win32 --enable-ipv6
--with-external-libmad --with-external-libdts --with-libflac --disable-v4l
--disable-arts --disable-artstest --without-caca --disable-cacatest
--disable-gnomevfs --disable-xvmc --disable-aalib --disable-aalibtest
--without-imagemagick --disable-gdkpixbuf --with-wavpack --disable-vidix
--x-libraries=/usr/local/lib --x-includes=/usr/local/include
--prefix=/usr/local --mandir=/usr/local/man --infodir=/usr/local/info/
--build=amd64-portbld-freebsd7.1
