Your system configured normally.  The instructions in the Wiki give you
the required prerequisites to install the base components.  In addition,
many components don't have any further requirements, so they get
configured for installation as well.  What you are seeing are optional
components that need further packages installed in order to compile.

The gr-audio-jack component requires the Jack audio library to be
installed; the default is to use ALSA, which is what your system
detected and used for audio.  The same is true for the portaudio component.

The OS/X and windows audio components will only work on those operating
systems, so this is normal.

Finally, gr-comedi requires libcomedi, but this is a specialized I/O
library for some obscure data acquisition hardware, so you likely don't
need that either.

So in short, you're good to go.  'make' and 'make check' should work
