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

[Wayne DePrince Jr.]

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
