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...
