lead up to SL

[Jeremy Huddleston]

I wasn't around during the leadup to Leopard, so I'd like a few  
pointers.  How should I be handling SL regressions in MacPorts during  
these coming months?  Should we have a special tag/keyword to place on  
radars?  trac doesn't support blocking/dependencies in bugs, so maybe  
a wiki page to track the big problems... ?

As it is right now, there are a few crucial ports that don't "just  
work" which block many others.  python2[56] don't work +universal nor - 
universal (at least on my system).  apr, gcc42, emacs, libsdl, libusb,  
libart_lgpl also fail.  I haven't really started diving into these  
build failures yet, so I don't know more than "it failed".

Additionally, should we update the default universal archs on SL?  As  
it is right now, on 64bit machines, -universal will be x86_64 and  
+universal is i386 ppc.  That will lead to a world of trouble.  I  
changed mine to x86_64 i386 ppc which seems to be the sane default for  
SL.
