 From man ld :)
-l namespec
Add the archive or object file specified by namespec to the list 
of files to link. This option may be used any number of times.  
If namespec is of the form :filename, ld will search the library 
path for a file called filename, otherwise it will search the 
library path for a file called libnamespec.a.

On systems which support shared libraries, ld may also search for 
files other than libnamespec.a.  Specifically, on ELF and SunOS 
systems, ld will search a directory for a library called 
libnamespec.so before searching for one called libnamespec.a.  
(By convention, a ".so" extension indicates a shared library.)  
Note that this behavior does not apply to :filename, which always 
specifies a file called filename.


So in this case it could probably work with -lphobos2.
Maybe -L-l:libphobos2.a was chosen to force the linking with the 
static lib (as can be seen in the second paragraph for systems 
that supports both).
