In that case, it's worth noting that you can shave a fair bit off the build time by not building gcc.  WITHOUT_GCC=yes in src.conf is worthwhile.  WITHOUT_GDB=yes is probably also sensible, as the gdb in base is so old that it doesn't understand most of the DWARF that clang uses.  We should have lldb ready for import in a few months, but until then using gdb from ports is more sensible if you plan on actually doing any debugging.

As we transition to a GPL-free base system, we're going to have some fairly long windows where we have the old GNU tool and its replacement both in base.  Over time, the old ones will be removed, but not until the newer ones are well tested.  This, of course, happens faster if people are running systems where they are the only option...
