Matplotlib: cannot use Tex anymore (Mac OS Sonoma)

I recently got a new laptop with Mac OS Sonoma 14.2.1, to which I migrated the data from my Big Sur laptop via TimeMachine. I updated Xcode and then followed the MacPorts instructions for migration (https://trac.macports.org/wiki/Migration). I also updated gcc to gcc 13.2 (https://github.com/fxcoudert/gfortran-for-macOS/releases), fortran code compiles fine.

The issue: matplotlib does not plot when using Tex. I get the following output:

    In [1]: p.plot([0,1],[0,1])    Installed osx event loop hook.    Out[1]: [<matplotlib.lines.Line2D at 0x16a8c70d0>]    In [2]: PANIC: unprotected error in call to Lua API (zlib library version does not match - header: 1.3, library: 1.3.1)    Traceback (most recent

Matplotlib's TeX implementation searched for a file named 'cmss10.tfm' in your texmf tree, but could not find it

The texmf tree is present in /opt/local/share/texmf-texlive/fonts/tfm. Running kpsewhich cmss10.tfm in the terminal gives the correct path. However, matplotlib.dviread can't find it.

I have explicitly put export TEXMFHOME=/opt/local/share/texmf-texlive/fonts/tfm and export TEXMFLOCAL=/opt/local/share/texmf-texlive/fonts/tfm in the bash_profile, this does not solve the issue. Plotting worked fine before updating Xcode and migrating macports...

Does anyone have any ideas to solve this issue? Thanks in advance!
