Sure. Here you go:

[1080/1080] cshlib: build/scipy/special/_cephesmodule.c.1.o
build/scipy/special/amos_wrappers.c.1.o
build/scipy/special/specfun_wrappers.c.1.o

build/scipy/special/cdf_wrappers.c.1.o
build/scipy/special/ufunc_extras.c.1.o ->
build/scipy/special/_cephes.so

No doubt everything in the runner list gets concatenated to form the
command line.
