Cryptography: cant install on debian with python3.6

[kakulukia]

i installed python3.6 on my debian box and am not able to install cryptography with this python version.
I installed that python version via the debian experimental branch.
The installation is possible under the system python3.4 tho. What might be missing?

Here is the error report:

pip install cryptography

The file referenced (/usr/share/dpkg/no-pie-compile.specs) is in the libdpkg-perl package on Debian, so installing that package should solve the immediate problem.

The fact that Python is trying to use it while building a C extension has to do with how you built Python (which I'm guessing you did yourself since there is no Debian version with both python3.4 and python3.6), so rebuilding Python 3.6 may also solve the problem, but I'd probably need to know more about how you did that to speculate further on the matter.
