[proaudio] media-libs/portaudio & pkg-config

[Harald Gutmann <harald.gutmann@xxxxxxx>]

hello!

i've a litte problem with the ebuild for portaudio-19-r2/3.
when i try to compile mixxx from svn, the compiller gets as an include
directory the following paths wich are a nonsense, because they're in
/var/tmp/:

"-I/var/tmp/portage/media-libs/portaudio-19-r2/image//usr/include 
-L/var/tmp/portage/media-libs/portaudio-19-r2/image//usr/lib"

the SConscrip from mixxx has the following command to detect installed
portaudio librarys:
pkg-config --cflags --libs portaudio-2.0

i think, that the includes from this command should be /usr/lib, because
portaudio gets installed there.
can someone of you be so kindly and fix this problem?

kind regards,
harald
