[kde-freebsd] xmlto->docbook dependency

[Dorian Büttner]

Hi list,

not sure if this is meanwhile fixed, it's been a handful of days since I built 
4.4.3 from ports. During fresh install rather than upgrade xmlto failed to 
build, since it expected docbook to be installed first (which wasn't 
automatically done).
Found out by some googling and manually installing docbook helped continue the 
build.

Regards,
Dorian
