Greetings.

I've been trying to reinstall Therion on a new M-series macbook on the newest OS (Tahoe) but have run into several 'dead ends'.

(1) First I tried the homebrew method, but I ran into the same issue as several others. The whole homebrew route seems to be broken currently.

(2) I tried to compile it from source, but it gets stuck while trying to compile Loch with the following error:

In file included from lxSetup.cxx:39:
./lxData.h:35:10: fatal error: 'vtkPolyData.h' file not found
35 | #include <vtkPolyData.h>
| ^~~~~~~~~~~~~~~
1 error generated.
make[1]: *** [lxSetup.o] Error 1
make: *** [loch/loch] Error 2

Does anyone know of a solution, how to tackle any of these problems by chance? Thanks in advance,
Anze
