 Double "hm".  BTW, I get:
 
 : {7} ; ls -l /proc/curproc/exe
 lr-xr-xr-x  1 root  wheel  7 Oct 22 15:31 /proc/curproc/exe@ -> /bin/ls=
 
 : {8} ; =
 
 
 Do you get something similar?

 Well, what can I say?  "It works for me."  I run my builds on a
 NetBSD/amd64 8.0 host.  The recent changes to the package's
 Makefile has been:
 
 30 sep -- update to 1.29.1
 08 oct -- fix "duplicate pre-build target"
 09 oct -- adjust URIs for ryoon binaries
 13 oct -- my major commit(s) with commented-out hooks for cross-buildin=
 g
 15 oct -- add pointers to (untested) sparc64 and earmv7hf bootstrap kit=
 s
 17 oct -- use ggrep, and adjust for SunOS
 18 oct -- fix WRKDIR reference
 18 oct -- apply fix for read-only source tree
 
 And ... I've not updated the amd64 bootstrap kit, so the bits you
 run from that should be the same ones as from before October 1.
 
 I just re-updated to HEAD in the package, and started a new
 native build for amd64, and the corresponding start of the build
 log in my case is:

 and it's still going (has progressed far beyond this point; it's
 doing the first LLVM build pass as I write this).
 
 Confused.
