Somehow I assumed that matplotlib itself was OK, but I just discovered
something new:

In [1]: import matplotlib.mathtext

Looking .../lib/matplotlib there are a few .so file and one is _png.so
(shipped by matplotlib) which seem to require libpng14:

        libdl.so.2 => /lib/libdl.so.2 (0x00007fad56373000)
        libutil.so.1 => /lib/libutil.so.

Does that give you any clue?

Thanks,

You might need to do a complete rebuild of your mpl trunk. I would guess that you originally built mpl when you had the older version of libpng. When you updated the library, that wouldn’t trigger a relink of _png.so whenever you rebuilt the trunk. Wipe out the _png.so file and rebuild.
