Question CT 7.2 & 7.3 don't build on Mac Intel Big Sur

Hello,
I tried to install CT 7.2 and Lab 7.3 on Mac Intel Big Sur (x86-64) ; system libraries installed fine, but when trying to build IDE it crashes : (3104) Compiling fcllaz.pas
Fatal: (10022) Can't find unit system used by fcllaz

Any idea ?

Thanks, regards.
