Thanks for sharing this. It is very much appreciated.

But how I see it, this is a bug in dh-python which handles removing / 
renaming shared libraries from the 
'debian/python3-med/usr/lib/python3.15/site-packages/med/' folder.

The fact that it doesn't know what to do with symlinks such as 
'_medfield.so.0 -> _medfield.so.0.0.0' is not the fault of med-fichier 
or the way it is built.

The med-fichier build was fine before the upload of dh-python 7.20261019.

What do you think?

Best,
_g.
