I think this makes a lot of sense too -- use-flag synchronization |
| 23 |
would probably be best handled outside of SLOT, otherwise we'd have to |
| 24 |
implement dynamic slots to get this properly supported. |
| 25 |
|
| 26 |
Now, that being said, it might be worthwhile if perl-module was |
| 27 |
expanded a bit in relation to the *DEPEND it adds -- having a |
| 28 |
PERL_MODULE_USES var or something, that could automatically append to |
| 29 |
IUSE (if necessary) and set the use-deps on dev-lang/perl, would make |
| 30 |
this a fairly simple implementation I think. |
| 31 |
|
| 32 |
Do all packages need to be rebuilt when some of these use flags |
| 33 |
change? Maybe auto-appending those particular flags (ithreads, debug) |
| 34 |
to IUSE and putting them on the dev-lang/perl dep is all that'll be |
| 35 |
needed, if this is the case. |

On an semi-related note, I have noticed that there are a fair number |
| 40 |
of ebuilds in the tree that are using perl-module at EAPI=4 and have |
| 41 |
'perl? (dev-lang/perl)' in *DEPEND, but are not setting |
| 42 |
GENTOO_DEPEND_ON_PERL=no before their inherit (and so perl is ALWAYS a |
| 43 |
dep). I'm thinking of filing bugs against all of these... |

Finally, thanks for testing!! I hope to improve the overlay a bit by |
| 48 |
the middle of next week, including a script that'll patch /var/db/pkg |
| 49 |
to simulate 4-slot-abi always existing (so one doesn't have to emerge |
| 50 |
- -e @world to get their environment ready to test). |
