Thanks. I think the list archive sufficient, no need for a bugreport.

Unfortunately, yes.

I've disabled all patches for now to not prematurely fail the build.

scantree.pl is a still a bit problematic even with doc_dirlist.patch
applied, the doc_vendor_install target fails because the
/usr/lib/x86_64-linux-gnu/perl5/5.22 directory doesn't exist yet. This
seems to be race condition with parallel make install.

I've patched Makefile.PL to use DESTDIR in the doc_*_install targets,
scantree.pl fails without trying to write
/usr/lib/x86_64-linux-gnu/perl5/5.22/PDL/pdldoc.db. It also fixes the
failure to find PDL.pm making doc_dirlist.patch obsolete, although we
may still need that for the trigger which uses scantree.pl too.

It did, I've done an extensive update as part of the changes for 2.016.

With the recent changes in git the package builds, but only with test
failures ignored. I'll look into fixing those where possible later.
There are also a bunch of lintian issues that need to be addressed. An
upload to experimental should happen soon, so we can start testing and
updating the reverse dependencies too (only libtfbs-perl is not
maintained by the Perl team).

There are now also git repositories for libpdl-io-hdf5-perl &
libpdl-netcdf-perl under the pkg-perl umbrella on Alioth, they're
populated with gbp import-dscs since no VCS appears to be in use for
these packages so far. I've not gotten around to updating these packages
yet, I'd like to get pdl ready for experimental first.

Kind Regards,

Bas
