Exactly.

That's usually caused by a build system which uses INSTALLDIRS=site,
which should be vendor ... And in practice left out in Debian since
our toolery sets it.

Here we are:

% grep -ir installdirs *
[..]
src/bindings/perl/Makefile.PL.in:              INSTALLDIRS => "site",


Oh, and then we have

src/bindings/perl/CMakeLists.txt:  set(PERL_PACKAGE_INSTALL_DIR ${CMAKE_INSTALL_LIBDIR}/perl5/site_perl/${PERL_VERSION}/${PERL_PLATFORM})

Ouch!


I'm attaching two patches (the first being hacky and without DEP3
headers) that seem to work, as in place the perl modules into the
right directory and getting the dependencies on perl(api) right.


Cheers,
gregor
