Actually, some inaccuracy here:

Since 0.99.2 or 0.99.3, Tango has installed libtango-base-dmd.a for DMD,
used via the -defaultlib switch. For GDC we indeed install libgphobos,
since there is no equivalent switch for GDC that also can be put in a .conf
file like with dmd.conf.

In both cases, you should not notice the use of that library, as it
happens "behind the scenes". So in the case of libgphobos - if the wrong
one is installed, Tango's runtime features will not work.
