Ok. So the file /Users/wilson/Library/Gentoo/usr/lib/libgomp.1.dylib |
| 33 |
does not exist. |

Right, I think gcc-config doesn't copy that lib to the place gcc is |
| 44 |
looking for it. I'm affraid the lib is installed in |
| 45 |
/Users/wilson/Library/Gentoo/lib/libgomp.1.dylib ... |
| 46 |
Can you verify that. I have to ponder a bit about this. |
