Hi John,

I already did pipe the build into tee, so I have a log. However, I
didn't find much libm in, unfortunately.

# grep libm.a buildworld.out

beastie# grep -E 'lib/libm([[:space:]]|$|/)' buildworld.out
===> lib/libm
/usr/obj/usr/src/world_x86_64/usr/src/lib/libm created for /usr/src/lib/libm

In /usr/local/lib, libm.a|so is present

beastie# ls -l /usr/lib/libm.*
-r--r--r--  1 root  wheel  492234 Jan  4 00:02 /usr/lib/libm.a
lrwxr-xr-x  1 root  wheel       9 Jan  5 09:56 /usr/lib/libm.so -> libm.so.3
-r--r--r--  1 root  wheel  126464 Jan  4 00:02 /usr/lib/libm.so.3
