Comment(by michaelld@…):

 I've reverted to 'zlib'.  I went over 'Configure' again & added all of its
 options as new variants.  I also looked up what all the variants mean &
 added that info to their description.  After a 'destroot' I was looking at
 the library dependencies of the libraries, executables, and engines, and
 noticed that the last incorrect referred to themselves without a full
 path.  So, I've added a "post-destroot" to correct those paths; no idea if
 it's truly necessary, but it works.  Anyway, give this new file a look
 over & see what you think.

 BTW> What started all of this was working on ticket #25652: for some
 reason this 'qca-ossl' release does not check to see whether openssl has
 md2 enabled or not.  Which got me wondering why it wasn't enable or at
 least a variant.  Which lead me to parsing through the Configure script.
 Which lead to the listing of default and experimental options as I've now
 included in this latest Portfile diff.
