You need to install a lot of GNU tools from exteranl sources (homebrew, MacPorts, Fink), so I do not see any problem in including bash into this list. My bigger problem is now, that there is no GNU linker available on OS X, so you need to use the LLVM linker which does not understand the -Wl,--as-needed flag. I need to dig deeper to understand since when GNU gcc set this flag by default and what the drawback is, if we remove this flag from the PTXDIST_HOST_LDFLAGS.

The exec with explicit fd numbers worked in a quick test on the command line.

I do not have access to the Mac right now. You will receive an answer later this day.
