The application will start, it won't have much functionality though.

I expect that people that compile from sources are able to find this
particular information in whatever tutorial they follow. Else that tutorial

If a user is confronted with make install needing more permissions than he
will just run sudo make install. People do that, without thinking because
it'll get them a result in no time. 

In fact IMHO every of our tutorials should suggest to install into
$HOME/foobar and then set KDEDIRS+run kbuildsycoca4.
