Made more progress with the build and install but now I am seeing 
issues with linking libphobos.

import std.stdio;

void main() {
writeln("hello");
}


Fails to link on FreeBSD with

/usr/local/lib/libphobos-ldc.a(runtime.o): In function 
`_D4core7runtime19defaultTraceHandlerFPvZC6object9Throwable9TraceInfo':

nm /usr/local/lib/libphobos-ldc.a | grep "backtrace_symbols"

U _D4core3sys7freebsd8execinfo17backtrace_symbolsFPxPviZPPa
U _D4core3sys7freebsd8execinfo20backtrace_symbols_fdFPxPviiZv

I see it here:
execinfo.d:42:extern (D) char** backtrace_symbols(const(void*)* 
buffer, int size)

Has druntime linked correctly in the phobos build? Would really 
like some guidance on how to debug this further.

Thanks
