"libmpfr.so.4" not found

[Patrick Welche <prlw1%cam.ac.uk@localhost>]

On one -current/amd64 box, I see e.g.

--- bt_close.d ---
/usr/src/tools/host-mkdep/obj/host-mkdep -f bt_close.d.tmp  --      -I. -I./include -I/usr/src/tools/compat -I/usr/sr
c/tools/compat/sys -DHAVE_NBTOOL_CONFIG_H=1 -D_FILE_OFFSET_BITS=64 -D__DBINTERFACE_PRIVATE     /usr/src/tools/compat/
../../lib/libc/db/btree/bt_close.c &&  mv bt_close.d.tmp bt_close.d
--- basename.d ---
Shared object "libmpfr.so.4" not found
--- atoll.d ---
Shared object "libmpfr.so.4" not found
--- bt_close.d ---
Shared object "libmpfr.so.4" not found


AFAICT there should never be a shared library for libmpfr, only a static one.

This probably has been happening for a while with no ill effect, but it
now seems to cause the recent xz tool to fail to build.

With /usr/obj on tmpfs I even see this after

cd /usr/src
umount /usr/obj
make cleandir
mount /usr/obj
mv /etc/mk.conf /etc/mk.conf.bak
sh build.sh -j12 tools 2>&1 | tee /tmp/build.log

Only clue so far:

cleandir ===> lib
sh: /tooldir.NetBSD-8.99.25-amd64/bin/nbsed: not found
make[2]: "../../Makefile.inc" line 17: warning: "/tooldir.NetBSD-8.99.25-amd64/bin/nbsed -ne "s/^PACKAGE_VERSION='\([^']*\)'/\1/p" /usr/src/external/bsd/file/dist/configure" returned non-zero status

No path before /tooldir.NetBSD...


Any of you seen something similar?

(Can't reproduce on another box.)
