Thanks for getting back to me on this!
Apologies for my lack of clarity:-)
I'm not a Mac user either. But I've seen this problem posted a few different
times. After using Macports to install Inkscape, everything looks like it was
working. But afterwards, they can't find Inkscape.
That is exactly what happened in my case. Can’t find anything named inkscape on my computer!
A bit frustrating overall, since I’m not really accustomed to doing stuff in Terminal. But it did look like everything was supposed to be OK.
