I had exactly these symptoms with my T30 at one point between 5.0 and
5.1. I got random failures in buildworld as well as in a few ports. I
never had any failures in normal operations and the errors were, when
closely checked, often things like unlinking files and changing file
attributes, not in the actual compile.

I fixed the problem by building a re-starting the build with
-DNOCLEAN. Eventually, the whole thing built. I had to make sure I was
not doing something that might leave damaged files around, especially
incomplete libraries, that would cause make to not rebuild them. It
did take a while.

Once I had built the new system and kernel, I installed them and
immediately did a complete rebuild of the system and kernel just in
case something was not quite right.

My T30 has been happily rebuilding 2 or 3 times a week since then with
no further problems.

Good luck!
