Just what I was afraid of, as I'm having a really hard time in having the
developers to pay any attention to this as 'sparc' isn't a supported
platform since they don't have any 'sparc' machines to work on. So I offered
to donate a Sparc machine to the project with Debian 6.0.1 loaded on it, so
they always have a sparc machine to test the releases on, or at least be
able to test it if someone reports a problem. But that wasn't much to
motivate them either. And unfortunately, I'm not a developer by any stretch
of the imagination so I can't go into the code to figure out howto fix this.
My only choice now is either they fix this OR I can figure out how to create
64-bit ssl libs that the make process finds compatible and moves the build
along. I even sent emails to the openSSL list, but a week has gone by and no
one has responded to it either.
