Comment (by michaelld@…):

 NP; really. Might be whack-a-mole; sometimes that works :) Fixing this
 might solve my problem too, it just hadn't occurred to me until reviewing
 yours that it could apply to mine.

 Anyway, you asked about naming. If you -always- plan on using cxx11, then
 I'd name them "/opt/libcxx" and "/opt/libstdcxx". If you want to be broad
 in scope, then name them "/opt/libcxx_cxx11" and "/opt/libcxx" (for
 whatever is not c++11); ditto for libstdcxx. In the latter, one can still
 do "-std=c++11" or not, so you'd want 2 directories for those, if you go
 that route.

 Good luck! Let's keep this ticket around just in case. I'm working on
 getting a box running 10.4 & 10.5 PPC (32 bit only), and another running
 10.5 / 6 / 7 / 8 Intel (for testing libcxx and libstdcxx, per your
 different install directories & then some specific settings). And then my
 primary laptop running 10.9 / 10 / 11 (for Intel 32 / 64, libcxx). I'm
 right now making good progress on 10.5 PPC; got Python up and running with
 an overnight build. It's a slow beast, but it does work (single core 1.6
 GHz PPC G5 iMac). I've got a 10.4 install disk that works, so once I get
 far enough along with the 10.5 stuff I'll create a new partition & have
 some fun going way back. i don't see a need to go to 10.3, but I think
 this mac supports it if I really wanted to. The main issue is that any
 Xcode prior to about 3.1 does not provide GCC 4.2, and getting it compiled
 will not be fun. 10.5 supports Xcode 3.1.4 which provides gcc 4.2 by
 default (yay!).
