[Pkg-d-devel] Libbiod and libundead packaged but sambamba does not build (Was: Next D project question: sambamba needs rdmd)

[Andreas Tille]

Hi Matthias,

thanks a lot for your commitment to this package.  Its really
appreciated since I'd otherwise would be totally clueless.

Thanks again.

I commited this patch to htslib git and build locally (even if
distribution is set to experimental I did not uploaded yet).

Hmmm, not at my side.  Despite I have changed

when trying to build sambamba in pbuilder I get

Is there any chance that you did not commited the last state of your
meson file?

I can perfectly do so but in any case feel free to commit those helpful
changes to Git if you have done those changes locally anyway.
 
I'd happily try the latter once the first issue is settled.

Thanks a lot again for your very great help
