problem in installation

[tamhanepd]

I am using ubuntu 14.04 LTS 64 bit. I am trying to install g3data on my laptop but it gives following error:

gcc -c -Wall pkg-config --cflags gtk+-2.0 main.c
gcc -c -Wall pkg-config --cflags gtk+-2.0 sort.c
gcc -c -Wall pkg-config --cflags gtk+-2.0 points.c
gcc -c -Wall pkg-config --cflags gtk+-2.0 drawing.c
rm -f .1
onsgmls g3data.sgml | sgmlspl /usr/share/sgml/docbook/utils-0.6.14/helpers/docbook2man-spec.pl
/bin/sh: 1: onsgmls: not found
FATAL: /usr/share/sgml/docbook/utils-0.6.14/helpers/docbook2man-spec.pl does not exist.
make: ** [g3data.1.gz] Error 2

I have installed the package sgmlspl. How can I get that file 'docbook2man-spec.pl'? I noticed that I don't have utils-0.6.14 directory inside docbook directory. I have only dtd and stylesheet directory. How can I get it?
