We need either gdc 2.067 or ldc 2.067 released in order to build ddmd with them. Otherwise we're suffering a 20% perf loss.
Note that this is a general problem, not limited to DDMD. We should definitively tie GDC and LDC closer to DMD dev. It is common for many to update to the latest version of DMD, usually because one need bugfix, and sugger that 20% slowdown because LDC and GDC are not ready.
