A more complete sequence is (with some
other text mixed in, as in where I got
the text from on ci.freebsd.org):

--- libvgl.a ---
building static vgl library
ar -crD libvgl.a `NM='nm' NMFLAGS=''  lorder main.o simple.o bitmap.o text.o mouse.o keyboard.o  | tsort -q` 
--- all_subdir_lib/libsysdecode ---
ranlib -D libsysdecode.a
--- all_subdir_lib/libvgl ---
ranlib -D libvgl.a
ranlib: fatal: Failed to open 'libvgl.a'
--- all_subdir_lib/libsysdecode ---
ranlib: fatal: Failed to open 'libsysdecode.a'
--- all_subdir_lib/libvgl ---
*** [libvgl.a] Error code 70

So, in essence,

ar -crD libvgl.a `NM='nm' NMFLAGS=''  lorder main.o simple.o bitmap.o text.o mouse.o keyboard.o  | tsort -q` 
ranlib -D libvgl.a
ranlib: fatal: Failed to open 'libvgl.a'

It is not obvious to me that the "Failed to open" means
that there was "no such file". Might there be some other
form of "Failed to open" for a file that does exist from
the ar at least having created its output .a file?
