Describe the bug Following error occurred while trying to start complied version of unbound with pythonmodule. Unbound version 1.13.2 OS: Ubuntu 20.4 Python: 3.8

root@####:/usr/local# /usr/local/unbound/sbin/unbound -vvv -c /usr/local/unbound/etc/unbound/unbound.conf -d [1629781639] unbound[223253:0] notice: Start of unbound 1.13.2. [1629781639] unbound[223253:0] debug: creating udp4 socket ... [1629781639] unbound[223253:0] debug: creating tcp4 socket ... [1629781639] unbound[223253:0] debug: switching log to syslog Traceback (most recent call last): File "", line 1, in File "/usr/lib/python3/dist-packages/unboundmodule.py", line 803, in class module_env(_object): File "/usr/lib/python3/dist-packages/unboundmodule.py", line 873, in module_env __swig_setmethods__["now"] = _unboundmodule.module_env_now_set AttributeError: module '_unboundmodule' has no attribute 'module_env_now_set'

To reproduce Steps to reproduce the behavior:

1. tar zxvf unbound-1.13.2.tar.gz
2. cd unbound-1.13.2
3. ln -s /usr/bin/python3 /usr/bin/python
4. ./configure --prefix=/usr/local/unbound --with-pyunbound --with-libevent --with-pythonmodule
5. make
6. make install
