Hi, Peter-
Thanks, I did an upgrade (not a clean install).
Yes, I downloaded the newest Xcode and the did the commandline tools install. I guess I have to see if some particular linked library is now 'bad' or changed version or something?
I used macports to get gcc48, and aliased that to be my gcc compiler. (Re. fink, which is what I used to use-- I believe that I would have to remove everything in my /sw directory, reinstall fink on the 10.9, and then redownload/stall everything again. That prospect is not very fun at this moment.)
I'm downloading the 10.7 build now, then, but I do have a keen interest in still being able to go from source...
Thanks for the advice,
pt
