Ha,I found the SHA1 problem. it was just a blankline in the distinfo file
introduced by make makesum. The other problem (man pages) is in one case
my fault, I didn't move the patch from files/ to patches/ and in the other
case the imake system does not work as I would expect.
The strangest effect is :
install -x -y Sourcedir /usr/X11R6/bin/../../bin 
which is /usr/bin in my case. I have no idea why this is because the lib
and the include files are installed where they belong.

P.S. Who am I going to send the pkgs if I succeed?
