When you mention it now I must say I did read about it somewhere along
the way it but I must have been already too tired to try something
else to fix the problem (I even had a different kernel installed,
that's how deseperate I got:).

Thanks for a lightspeed answer. Too be honset I've never used this
kind of communication (mailing lists as a traditional communication
fan - face2face, telephone:) so I'm not sure I should be starting a
new (discussed here some time ago I think) topic meaning xmlto - I
mean the fact that in order to install openswan from source (which I'm
also a fan of) along with the man pages you have to have it installed
which is, well, unpleasant since then Ubuntu forces you to install
dozens of other packages (more than 200 megabytes). I guess you could
exlude some of them but that's just another set of commands and a
possibility of ruining the whole process after all. Installing xmlto
manually isn't cool either (too be honest I gave up after 30 minutes)
cause it depends on other packages which depend on other packages and
so on. So as not to say too much in this thread: is there an option
*not* to install the man pages? Because I couldn't find anywhere and
AFAIR you did comment on someone else's sorrow concerning xmlto saying
that you'd add such an option in a future release. ;)
