poudriere: build failing permanently for lang/python27

[O. Hartmann]

My setup is as follows:

the base system is most recent CURRENT (as of today, FreeBSD 11.0-CURRENT #2
r296556: Wed Mar  9 06:50:02 CET 2016 amd64). The used jail is a
built-from-source 10-STABLE, as of today, also. The ports tree is head and also
up to date.

Building a ports tree (customized/selected, not the whole FreeBSD's ports tree)
works fine using a jail running HEAD as denoted above. But using the same
(vanilla) configs (src.conf, make.conf) with the 10-STABLE jail, port
lang/python fails in staging the port:

Python build finished, but the necessary bits to build these modules were not
found: _bsddb             _sqlite3           _tkinter

linuxaudiodev      spwd               sunaudiodev     
To find the necessary bits, look in setup.py in detect_modules() for the
module's name.

What is wrong here? Am I mistaken that I can build on CURRENT by using a
10-STABLE jail a ports tree dedicated to 10-STABLE?
