Weird. It looks like media_build misinstalls this. If altera-stapl is in
the wrong place, then I suspect the other modules are also in the wrong
place and thus duplicated, which will cause all the things you see below.

Which distro are you using?

Anyway, I would recommend that you make a safety copy of your modules
first (just in case :-) ), and then move all the newly install modules
to the right place.
