... yatiblog wanted an ubuntu package, and It Would Be Nice if they could play together. Anyway, the fix:

$ sudo pip install -U docutils
...
> Successfully installed docutils

$ sudo pip install -U yatiblog
...

surprisingly long, but I resisted scrollblindness long enough to notice

>     libyaml is not found or a compiler error: forcing --without-libyaml

whereupon I hit C-c, then

$ sudo aptitude install libyaml
...
> Couldn't find package "libyaml".  However, the following packages contain "libyaml" in their name:
>   libyaml-tiny-perl libyaml-appconfig-perl libyaml-syck-perl libyaml-dev libyaml-ruby libyaml-0-1 libyaml-0-2 libyaml-ruby1.8 libyaml-libyaml-perl libyaml-perl

"libyaml-libyaml-perl" ?-) I guessed

$ sudo aptitude install libyaml-dev
> The following NEW packages will be installed:
libyaml-0-2{a}
libyaml-dev
...

$ sudo pip install -U yatiblog
...
> Successfully installed yatiblog

$ which yatiblog
> /usr/local/bin/yatiblog

Onward to usage, thanks for the pointer, Tom Roche <Tom_Roche at pobox.com>
