Build fails on Linux (Debian Testing)

[tcrass]

Hi there,

just tried to build MISST V3.1.0 on an up-to-date Debian Testing (to this date: aka Trixie) installation, which uses python 3.13 by default, following the instructions from https://github.com/Frikallo/MISST/#manual-installation.

First two remarks regarding the instuctions (step 3):

1. It says that the commands should be run from the MISST directory. This is somewhat misleading since the directory containing the requirements.txt file is the archive's root directory MISST-x.y.z, of which MISST is a sub-directory. So step 3 should rather be something along the lines of "Open the command prompt from the MISST-x.y.z directory [...]".
2. After creation, the venv should also be activated prior to calling pip install: $ source venv/bin/activate.

Unfortunately, the install command fails for me with the following output:

      performance hint: src/gevent/libev/corecext.pyx:1339:0: Exception check on '_syserr_cb' will always require the GIL to be acquired.
      Possible solutions:
          1. Declare '_syserr_cb' as 'noexcept' if you control the definition and you're sure you don't want the function to raise exceptions.
          2. Use an 'int' return type on '_syserr_cb' to allow an error code to be returned.
