Re: Installing NCL 6.2.0 on Mac OS 10.7.5

Hello,

I just wanted to share that I'm facing a similar situation with my
desktop Mac. It's just one hardware generation too old for 10.8 or 10.9
and thus currently not able to go to NCL 6.2. I have experience doing
complex from-source installs but haven't felt ready to tackle 6.2 yet
(it is not trivial). I'm also pondering a system "hack" that is
supposed to make it possible to install 10.8 on my Mac Pro, in which
case I might not have to deal with the from-source install after all
(see my postscript for links).

I admit I haven't thought through all the implications, but I'd be
willing to consider making this machine available to the NCL folks to
get a 10.7 binary out there. I understand that this might not be a path
you want to take though :-)

Cheers,
Dave

P.S. Those of you with older Mac Pros might find the following links of
interest. I have *not* tried any of the suggestions nor am I in any way
able to answer questions about them. This is just a "public service".
