Description of problem:

Using the Fedora 34 package (blender-2.93.4-1.fc34.src.rpm), all 'Color Management' options under the 'Render Properties' are missing. Using the blender.org download all options are found as expected.

A possinle cause:  
Upon starting the executable in a shell, error messages about color management and OpenColorIO are produced. An RPM ChangeLog entry states:

    * Wed Sep 01 2021 Richard Shaw <hobbes1069> 1:2.93.3-9
    - Rebuild for OpenColorIO 2.1.

Fedora 34, however, seems to provide OpenColorIO 1.1.1.


Version-Release number of selected component (if applicable):

2.93.4-1.fc34


How reproducible:


Steps to Reproduce:
1. Start package provided Blender
2. Navigate to Render Options (by default right-side lower section, 2nd tab from top), scroll to end of tab, expand Color Management
3. Click on View Transform, note multiple missing options (e.g. Filmic)
4. Click on Look, not multiple missing options
5. Build a scene and attempt to modify Exposure, Gamma; note lack of change (use viewport shading: rendered)



Actual results:

Multiple missing options and functionality under Color Management.


Expected results:

View Transform dropdown should contain False Color, Raw, Filmic, Filmic Log, Standard. Look dropdown should contain multiple contrast options. Exposure, Gamma sliders should affect (rendered shading) lighting. 


Additional info:

Suspected culprit: package compiled against OCIO 2, F34 supplies OCIO 1.  
(Separately, Blender has previously encountered problems with paths containing more exotic UTF-8 characters, leading to similar problems when required data files are not found, but this presumably is not the issue here.)
