Building the docpack in Documentation/DocBook/

[Sunalla, Aladdin]

Hi All,
	I am running with Linux 2.6.8 for PPC.  I can not seem able to build
the docpack that is available in the /usr/src/linux/Documentation/DocBook, I
get the following error message:

[root at dhcp-10-1xx- DocBook]# make pdfdocs
*** You need to install DocBook stylesheets ***
make: *** [/wanbook.pdf] Error 1

Anyone knows what this error means?

Thanks,
Aladdin
