lang/oracle-jdk8 distfile for Mac OS

[Brook Milligan <brook%nmsu.edu@localhost>]

I am trying to install lang/oracle-jdk8 on a Mac OS system.  The intended distfile is jdk-8u152-macosx-x64.tar.gz.  However, Oracle seems to be distributing only *.dmg (not *.tar.gz) files for the JDKs (unlike the JREs).

How should this be addressed?

Cheers,
Brook
