Comment (by kencu):

 so far I've had no luck with this using libcxx with 10.6; something I saw
 in the comments on a page in the libcxxabi code review portal suggested
 that perhaps 10.6 couldn't be supported with TLS, but at the moment I
 can't re-find that page.

 Perhaps of some interest, libgcc's stdlibc++ does appear to support TLS on
 10.6 (successfully building and running the software I was trying use,
 glbinding, so there is something to ponder if one really needs TLS and is
 prepared to go through a few hoops.
