| # @ECLASS-VARIABLE: CONFLICT_LIST |
| # @DESCRIPTION: |
| # Atoms mentioned in CONFLICT_LIST need to either be unmerged or upgraded |
| # prior to this package being installed, but we don't want to have an explicit |
| # dependency on that package. So instead, we do the following: |
| # 1. When we are installed, ensure that the old version is not installed. |
| # 2. If old version is installed, ask emerge to consider upgrading it. |
| # This consideration is listed as PDEPEND so that we don't add an |
| # explicit dependency on the other package. |
| for atom in $CONFLICT_LIST; do |
| DEPEND="$DEPEND !!<=$atom" |
| RDEPEND="$RDEPEND !!<=$atom" |
| PDEPEND="$PDEPEND || ( >$atom !!<=$atom )" |
| done |
