Sponditious.

They work for me fine on a MBP with OSX Mavericks.

However on a white MB with OSX Lion (*) the install of DMD fails. The
problem appears to be that Clang cannot link the object files since the
object files are not built for x86 architecture – despite the processor
being 64-bit, the boot prom is 32-bit and so OSX is 32-bit and reports
the processor to be 32-bit, unlike the processor which knows it's 64-bit
and reports so. As far as I can tell (log files are huge due to the huge
numbers of warnings about expressions) all the clang++ lines have
-DDM_TARGET_CPU_X86, so I am somewhat surprised. Of course I am really a
Linux person being forced to set up OSX boxes for testing…

I think this is a core problem for D in general: everyone needs or wants
shared libraries, but…



(*) Apple refuse to allow any upgrade of this hardware to OSX Mountain
Lion or OSX Mavericks, so I am stuck with OSX Lion.
