I have just updated current pkgsrc tree, bootstraped it, started building
packages and this is what I got. Anyone knows what the problem is?

bmake: don't know how to make /usr/lib/libc.a. Stop

bmake: stopped
in /opt/pkg.obj/pkgtools/pkg_install-info/work/pkg_install-info-4.5 *** Error
code 2

Stop.
