I have a (possibly) naive question about building world from source.
Yesterday I supped allsrc from the release-1-5 collection.  I built a kernel
with no problems (id's itself as 1.5.3_ALPHA) and then tried a 'make build'.
This died with the horrific message below:

I thought anything from one of the stable release collections would build
'out-of-the-box'; I was under the impression that only '-current' might fail
to build.  Is the above indicative of a bootstrapping problem or something
more severe?
