In order to have two versions of the same package on a system at the |
| 54 |
same time, the system has to be able to figure out which is which. That |
| 55 |
is what Gentoo calls slots. Here, I have python 2 and 3 installed. I |
| 56 |
have the system set to python 2, with eselect, but some packages CAN use |
| 57 |
python 3 if it so chooses. Maybe this link explains it better: |
