[Debian-med-packaging] Bug#1092510: RFS: python-freecontact: FTBFS: ImportError: /lib/x86_64-linux-gnu/libboost_python313.so.1.83.0: undefined symbol: PyObject_DelAttr

Control: tags -1 patch

Hi,

This is due to an improper version of boost linked against 3.12 .so of
freecontact. The work-around for linking boost in d/rules is wrong when
there are more than 1 python version.

The below patch links the correct versions and gets it building.

+Description: boost python libs are versioned. Simply using
liboost_python does not work.
+ Added in a small function to return proper boost version as per
interpreter
