Установка KRadio4 (проблема с зависимостями)

Решил установить вот эту замечательную программу:

http://kradio.sourceforge.net/

Проблема возникает с подержкой Internet Radio Stations (собственно, то что мне нужно от этой программы в первую очередь). Вот вывод CMake:
...

В инете нашел совет, что нужно установить libav*-dev. Вот что выдает aptitude, при попытке установить, например, libavformat-dev:
$ sudo aptitude install libavformat-dev
[sudo] password for pilat:

Accept this solution? [Y/n/q/?] q

Подскажите, пожалуйста, есть ли способ установить "девелоперские" файлы, не трогая "рабочие" либы, рекомендуемые для пакета kubuntu-restricted-extras (типа libav*-unstripped-51)? Или они друг-друга реально заменяют?

Поддержки чего я лишусь если откажусь от "libav*-unstripped-51" пакетов?
