Wrong SFCGAL version used for compiling PostGIS 3.6.0 on Ubuntu?

Hi,

I noticed 3.6.0 became available on Ubuntu 24.04 where I am currently 
running my PostgreSQL / PostGIS install.

However, after adding the 'postgis_sfcgal' extension and the PostGIS 
extension upgrades using "SELECT postgis_extensions_upgrade();", 
attempting to use the new 'CG_Simplify' function that requires SFCGAL in 
as SQL statement, leads to the following error:

"SQL Error [XX000]: ERROR: The SFCGAL version this PostGIS binary was 
compiled against (10501) doesn't support 'sfcgal_geometry_simplify' 
function (requires SFCGAL 2.1.0+)"

Is this is a possible error during the packaging for the latest release 
for Ubuntu?

Marco
