Hey guys, I found my problem a few days ago and forgot to tell everyone. I 
had CPPFLAGS and LDFLAGS set in my environment...  I didn't realize they 
were set, and section 5.2 only has you unset CFLAGS and CXXFLAGS.  Glad I 
fixed it, but sheesh that took forever to track down.

Might I suggest that section 5.2 also explicitly unset these two?  ;-)
