So long as you add to DEPEND unconditionally, the issue that Martin |
| 11 |
pointed out does not apply. If you need to fudge the conditional, you |
| 12 |
can put it behind a USE flag; for example, |
| 13 |
|
| 14 |
DEPEND+=" some_use_expand_flag_foo? ( foo )" |
| 15 |
|
| 16 |
in the eclass. That's still adding to DEPEND unconditionally, even |
| 17 |
though its effect on the dependency tree (at "emerge" time) is |
| 18 |
conditional on the USE flag. |
