Comment (by lpagani91):

 I am still having the same problem in 2026 as what I mentioned in
 #69350...

 I am now running with Macports 2.12.5 environment, made a fresh reinstall
 of all my ports.
 Since pyopencl crashes at start in python3.11 and is not available for
 python3.14 inside Macports, I collected it using PIP-3.14 :

 {{{

 I tested that i could import pyopencl in python3.14

 {{{

 >>> import pyopencl

 }}}

 however, trying to run the test.py mentioned in
 [https://trac.macports.org/ticket/69350#comment:1] still crashes :

 However, since this is not directly linked to Macports anymore, you might
 consider it is none of your business... Fair enough. Simply, I wonder
 whether a true Macports install of pyopencl in Python 3.14 would help ?
