Hello Mac-Users,

I am running Mac OS X 10.8.2 Mountain Lion and Sketchup 8 Pro and came across installation problems.
I installed LibFredo6_46 and RoundCorner_23 by extracting it with "Forklift" (Replacement/addition to finder) into /Library/Application Support/Google SketchUp 8/SketchUp/plugins (including all the subdirectories).
To do this I had to enter my root-credentials.
After restarting SU an error dialogue popped up saying that the directory
/Library/Application Support/Google SketchUp 8/SketchUp/plugins/DEFPARAM_Dir
was still missing. So I touch that empty directory (again with my root credentials).

After that SU starts up without error and even the toolbar of Round Corners shows up, but the toolbar (when activating / clicking on the 3 icons) didn't show up. FredoLib didn't come up with errors either -> very annoying since it wasn't working.

I OVERCAME the problem by recursively changing the permission of the plugins-directory to 777 on the console.
Afterwards it worked perfectly.

I hope this helps you guys....

Cheers - and thanks to fredo for this cool plugin!!!
