I tried building libwx-perl on armel / abel.debian.org in a jessie chroot
(the build dependencies are uninstallable in sid right now), with gcc-4.9
4.9.1-16, and still got
t/01_load.t ........... 1/6 Can't load '/home/ntyni/libwx-perl-0.9923/blib/arch/auto/Wx/PropertyGrid/PropertyGrid.so' for module Wx::PropertyGrid: at /home/ntyni/libwx-perl-0.9923/blib/lib/Wx/Mini.pm line 74.
which looks like the problem is still present.
But we probably need the wxwidgets3.0 packages built with a fixed
gcc-4.9 first? This was jessie's 3.0.1-3, and buildd logs say it was
built in August with 4.9.0-10.
I've filed #764525 to fix the uninstallability in sid and can re-test
when the binNMUs are built. The porter box setup doesn't really allow for
manually built binaries or mixing distributions AFAICS.
