I confirm this behavior on a fresh install of version 5.9 from the

In version 5.8, it did not. Don't know the reason for this...
FWIW, it did still work in 5.9.beta2.
Probably #13031 [1] (merged into 5.9.beta4), or one of its follow-ups(?)
is to blame...
For the impatient, the following at least avoids rebuilding of (most of
the) Cython-generated files:
diff --git a/sage-clone b/sage-clone
--- a/sage-clone

(To be applied to the Sage scripts repo, in $SAGE_ROOT/local/bin/.)
It seems also all(?) Python files get re-(byte-)compiled; don't know yet
why... (but the latter doesn't take as long as re-"cythonizing"* does)

Hi,
It seems that the behavior of "sage -clone" changes around the
version 5.9. I freshly compiled a version of 5.10.beta2 and when I
do a clone it recompiles the wholse sage sources (but hopefully not
the auxilliary spkg). The first line in the log of "sage -clone"
which differs from previous version is the following
Updating Cython code....
Compiling sage/algebras/quatalg/quaternion_algebra_element.pyx
because it depends on ./sage/structure/sage_object.pxd
...
I was not able to find some information elsewhere.
Best,
Vincent
