This means that the python-binding will be broken anyway:

>>> from graphviz import *;
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/local/lib/python2.3/site-packages/graphviz/__init__.py", line 23, in ?
    from graphviz import *
  File "/usr/local/lib/python2.3/site-packages/graphviz/graphviz.py", line 5, in ?
    import _graphviz
ImportError: Shared object "libagraph.so.0" not found, required by "_graphviz.so"

Having spent the last week in -rpath-hell anyway, how about this solution:
-       ${CC} -shared ${LOCALBASE}/lib/graphviz/libagraph.so ${LOCALBASE}/lib/graphviz/libcdt.so gv_wrap.o -o _graphviz.so
+       ${LD} -shared -L${LOCALBASE}/lib/graphviz -rpath ${LOCALBASE}/lib/graphviz -lagraph -lcdt gv_wrap.o -o _graphviz.so

This makes the use-case above work again and doesn't require and ldconfig.
I'll check if there are any other consumers of graphviz' shlibs.

#readelf -a work/graphviz-0.1/_graphviz.so | grep PATH
 0x0000000f (RPATH)                      Library rpath: [/usr/local/lib/graphviz]
# ldd work/graphviz-0.1/_graphviz.so
work/graphviz-0.1/_graphviz.so:
        libagraph.so.0 => /usr/local/lib/graphviz/libagraph.so.0 (0x28119000)
        libcdt.so.0 => /usr/local/lib/graphviz/libcdt.so.0 (0x28128000)
