Hello Thomas,

Thanks for looking at this, I'm currently far behind on many things and 
not very responsive:-(

Plenty files and links, eg:

      0 lrwxrwxrwx 1 fabien fabien       21 janv. 23 09:40 /home/fabien/clgtk/lib/libLLVMMCJIT.so ->
libLLVMMCJIT.so.12git
   2140 -rw-r--r-- 1 fabien fabien  2190824 janv. 23 09:28 /home/fabien/clgtk/lib/libLLVMMCJIT.so.12git
      0 lrwxrwxrwx 1 fabien fabien       22 janv. 23 09:40 /home/fabien/clgtk/lib/libLLVMOrcJIT.so ->
libLLVMOrcJIT.so.12git
  40224 -rw-r--r-- 1 fabien fabien 41187208 janv. 23 09:34 /home/fabien/clgtk/lib/libLLVMOrcJIT.so.12git

Hmmm, clang recompilation has been failing for some weeks. Argh, this is 
due to the recent "master" to "main" branch renaming.

No such file of directory:-) because the directory is cleaned up.

Argh. Would it be so stupid? :-( I thought the configuration stuff would
manage the link path automatically, which may be quite naïve, indeed.

Hmmm. I've tried that before. I can do it again.

I've added an explicit LD_LIBRARY_PATH, which will be triggered at some 
point later.
