[reSIProcate] MacOS 10.4.8 / Intel

[Adam Roach]

I'm hardly an expert on the OS X linker, but I'm a bit suspicious of 
your link line when building the libsipdial.dylib.

I *think* you want "-undefined dynamic_lookup" instead of "-undefined 
warning". I believe the latter requires the symbols to be already linked 
in at runtime, while the former will cause them to be loaded if they 
don't exist. (This requires the use of "-twolevel_namespace" instead of 
"-flat_namespace", but I suspect you should probably be using a 
two-level namespace anyway unless you have a really good reason to use 
the older style flat namespaces).

In any case, the missing symbols in building the library are only 
warnings, not errors. If you need to stick with the flat namespace, you 
can eliminate the (mostly useless) spurious out put with "-undefined 
suppress"
