Ok so you and others can build the jdks fine on 7.0R. I guess I'm out of
ideas as to why Scott and Nicolas's systems don't record the dependency
on libthr.so.

In 1.6 the debug portion of the build can be optionally turned off using
SKIP_FASTDEBUG_BUILD="true" which is the default. In 1.5 the hotspot
debug binaries are always built (although only installed if the port
DEBUG option is on).
