In poudriere each port is built independently, that is they don't
inherit the specified python version from the port triggering the build
as a dependency. It is possible that poudriere could be adjusted to
compensate for this. It would require considering PYTHON_VERSION and
using pkg names when dealing with dependencies instead of just the port
origin. So, yes to a poudriere bug.

For now - to get ports to build in poudriere with python3 you need to
create a make.conf for the poudriere jail -
/usr/local/etc/poudriere.d/jailname-make.conf

To get all ports built with python3 as the default version add

DEFAULT_VERSIONS= python=3.5

To get python3 ports that install into a system that has py2.7 as
default you need to have

DEFAULT_VERSIONS= python=2.7 python3=3.5
PYTHON_VERSION= python3.5

As the default python is still 2.7 I believe the port will need to
define IGNORE. Something like -

.if defined(PACKAGE_BUILDING) && ${PYTHON_DEFAULT} == 2.7
IGNORE= requires python3 dependencies and must be built manually
.endif
