Greg,

You are misreading the above.  The -L/usr/local/lib directive tells
the linker to look *first* in /usr/local/lib for libraries and then fallback
to the usual locations - normally /usr/lib.  It does not mean that all the
following libraries are expected to be found in /usr/local/lib.  Often the
configure logic puts a mismash of -L directives in the link directives
which can result in link time problems.

Best regards,
