V --

Thanks for pointing out this fix but I'm a little bit confused.  You;re talking about libvisio and libcdr but your local
libvisio-devel and libcdr-devel ports appear to be correspond to the latest MacPorts ports libvisio-0.1 and libcdr-0.1
but built from git master.  Am I correct?

I don't have a platform to test on Lion at this point so I wonder if you could check and verify that this issue applies
to all four MacPorts ports libvisio, libvisio-0.1, libcdr, libcdr=0.1 and perhaps librevenge separately?

Which version(s) are you using to build Inkscape OSX releases?  I'm planning to drop the older non-librevenge versions
as soon as they are not needed by other dependents.  Is this a problem for you?

Thanks again for your help
