First of all `clang` python module tries to find not versioned libclang but `libclang.so` so I've added below quick patch
```patch
--- a/clang/bindings/python/clang/cindex.py
+++ b/clang/bindings/python/clang/cindex.py

elif name == "Windows":
file = "libclang.dll"
else:
- file = "libclang.so"
+ file = "libclang.so.17.0"
if Config.library_path:
file = Config.library_path + "/" + file
```
Unversioned library name is part of the clang devel resources.
Than on use installed `clang` module it tries to find `libclang.so.17.0` in /usr/local/lib.
Below is from building libdicom documentation"

Please also report this if it was a user error, so that a better error message can be provided next time.

```
At the same time in system is installed
```console
[tkloczko@pers-jacek SPECS]$ ls -1 /usr/lib64/libclang*
/usr/lib64/libclang-cpp.so.17.0
/usr/lib64/libclang.so.17.0
/usr/lib64/libclang.so.17.0.4
```
It would be good to find better way to update LLVM major version number in libclang library name than what is in above JFDI patch
