I haven't been able to build a -current release for i386 or macppc
since Apr 18:

This is using:
/usr/src/build.sh -x -r -U -u -m i386 -D /opt/obj/i386/build -M /opt/obj/i386 -T /opt/obj/i386/tools -R /opt/snapshot tools release

where I clean out /opt/pbj/i386(macppc) entirely and have deleted
and re-checked out src and xsrc from cvs. This has been working
for some time without problems. Are others having troubles with
this?
