/usr/ports/textproc/gnome-doc-utils not build

[Horacio Matias]

Hi all
I try to install gnome-doc-utils from /usr/ports/textproc/gnome-doc-utils
freebsd port, but when typing make install clean* *I have the following
error:

gmake: *** [Makefile.in] Error 1
*** Error code 1

Stop in /usr/ports/textproc/gnome-doc-utils

This is the $FreeBSD line from Makefile:

$FreeBSD: ports/textproc/gnome-doc-utils/Makefile,v 1.31 2010/12/26 16:05:45

And port version gnome-doc-utils-0.20.3

I have FreeBSD 8.2 amd64. I attached the image of the error.

Thanks for your help.
Sorry for my english
