Some additional details about this: A fresh darcs pull followed by "scons 
type=release" currently produces the mentioned error. But if I then do "scons 
build library type=release", that appears to succeed. And if I then repeat 
the "scons type=release", additional stuff gets built. But the end result of 
all this is a yhc that passes the usual tests.

Summarizing, "scons" seems to be somehow different from "scons build yhc" + 
"scons build yhi" + "scons build library".

And a question here: The buildbot uses "scons ...snapshot=1", what does that 
mean?

This is now issue #122 and there is even a patch that fixes it.
