The packages "which" and "ncurses" are needed for building pygobject3
(on darwin) during the checkPhase. The ncurses library is necessary only
because python3.5 is currently built using "-lncurses" and pygobject3
wants the same libraries that python3.5 was compiled with. (Because it
uses "python3.5-config --ldflags" during the build)
Compiling python with "-Wl,-stack_size,1000000" causes problems when
compiling for example pygobject3. pygobject3 uses "python3.x-config
--ldflags" during installation and then fails when
"-Wl,-stack_size,1000000" is present. Maybe we should investigate
removing this during the build of pyobject3, but this stack_size flag is
also not used on the popular darwin homebrew-core channel for python3.5,
so it seems safe to remove it.
After splitting the DejaVuSans.ttf file into a multiple output in the
dejavu_fonts Nixpkgs expression it is not possible to install in the
user profile due to the collision. The attached patch makes a new
package without the collision for user environment installing.

Subject: [PATCH] dejavu-fonts : Prepare an environment package without
collision.
Fixes build against dpdk 16.06
Tested build against linux, linux_latest, linux_3_18, linux_4_1,
linux_4_6, linux_grsec_nixos, linux_chromiumos_3_18.
While this is pre-release, the delta since 10.10.1.0 seems to contain
primarily fixes or internal improvements.
Also cleanup build inputs while we're at it.
I don't know why the builder uses `lndir ${dbus-python} $out`,
but this commit should work around the problem caused by
dbus-python starting to propagate some inputs.
Looks to be incompatible with the PaX constification plugin:
