[proaudio] media-sound/ladish-1-r1 not building

["Wayne DePrince Jr." <waynedpj@xxxxxxxxxxx>]

ahoy all,

    it seems like ladish with USE python enabled is trying to pull in lash via pylash though i have -lash set for USE flags:

pylash build was requested but liblash was not

i am no ebuild expert and admittedly the problem could be with my setup, but looking at the ebuild i believe the error is in the following line in src_configure:

$(usex python --enable-pylash "")

it seems like using python implies using lash.  thus, would it make sense to have something like

$(usex python "--enable-pylash --enable-liblash" "")

or do the use flags need to be changed so enabling python also enables lash, maybe using REQUIRED_USE

REQUIRED_USE="${PYTHON_REQUIRED_USE}
	      python? ( lash )"

    basically, i am unclear about what the intention is: does the python USE flag only matter if lash is also enabled, or does enabling python w/o lash also make sense?  i am assuming the latter (i.e. that having python/pylash w/o lash does not make sense) and so i have attached a new ebuild where python USE flag only makes sense with the lash USE and thus has the above REQUIRED_USE to ensure that.

    thanks in advance.

peace, w
