Tango Problems..

[Rémy Mouëza via Digitalmars-d-learn]

 From what I understand in the error message, the linker cannot find a 
druntime function: void core.stdc.stdarg.va_end(void*).

I would advise to check that the druntime lib is in the import path.
In your the dmd repository, you should have a dmd.conf file containing 
something like:
[Environment64]
DFLAGS=-I%@P%/../src/phobos -I%@P%/../src/druntime/import 
-L-L%@P%/../lib64 -L--export-dynamic

(%@P% means the compiler path).
This should help you to fix your command line adding for instance:
-I/usr/local/lib/dmd/druntime/

In my dmd installation (2.066.0), the druntime is contained in 
libphobos.a/libphobos.so. Are you linking with libphobos?
