Actually on darwin this isn't that simple. If you use --with-local-prefix= set
to anything other than /usr/lcoal, a potential header/library mismatch
situation is made possible because the compiler no longer searches
/usr/local/include for headers bu the linker command does still search
/usr/local/lib. Fortunately, this glitch is trivial to solve without resorting
to the --with-local-prefix hack. The simple change...
