This is a bug in how TYPE? is recognized. The goal is if TYPE? is not
(lexically) defined, but TYPE is *and* TYPE is typed-value, then we
get '(lambda (obj) (instance? obj TYPE))' The problem is the test
for 'TYPE is type-valued' is missing. See the FIXME comment in
checkDefaultBinding in SchemeCompilation.java.

Looks like your using the old Subversion repository. You should switch to
the Git repository.
I intend to check in the the Subversion repository a change so
it no longer builds by defauilt.
