There's something strange in the '-L' options.  How come three zlib11s
and no libpng12?

You might be able to see why the second /opt/TWWfsw/zlib11/lib/pa20_64
occurs in the path using -Wl,-v.

You are correct that "+b" is explicit and there may be times when you
you don't want a "-L" directory in the embedded path.  I wonder if 
libtool could check for a user "+b" option and append the specified
path to the accumulated rpath.
