I know. Except that in virtual/libgudev-215-r3.ebuild we have in the DEPEND: |
| 22 |
>=sys-fs/udev-208-r1:0/0[${MULTILIB_USEDEP},gudev(-),introspection(-)?,static-libs?] |
| 23 |
It is a 2-style dependency (following the PMS). |

I checked with 3 dummy packages |
| 26 |
|
| 27 |
1. app-misc/dummy-master-1 |
| 28 |
EAPI=6 |
| 29 |
SLOT=0 |
| 30 |
KEYWORDS="amd64" |
| 31 |
IUSE="static-libs" |
| 32 |
DEPEND=">=app-misc/dummy-slave-1[static-libs?]" |
| 33 |
#DEPEND="=app-misc/dummy-slave-1[static-libs?]" |
| 34 |
|
| 35 |
2. app-misc/dummy-slave-1 |
| 36 |
EAPI=6 |
| 37 |
SLOT=0 |
| 38 |
KEYWORDS="amd64" |
| 39 |
IUSE="" |
| 40 |
DEPEND="" |
| 41 |
|
| 42 |
3. app-misc/dummy-slave-2 |
| 43 |
EAPI=6 |
| 44 |
SLOT=0 |
| 45 |
KEYWORDS="amd64" |
| 46 |
IUSE="static-libs" |
| 47 |
DEPEND="" |
| 48 |
|
| 49 |
With the first version of DEPEND, emerge succeed: |
| 50 |
# emerge -pv app-misc/dummy-master |
| 51 |
|
| 52 |
These are the packages that would be merged, in order: |
| 53 |
|
| 54 |
Calculating dependencies... done! |
| 55 |
[ebuild N ] app-misc/dummy-slave-2::gentoo USE="-static-libs" 0 KiB |
| 56 |
[ebuild N ] app-misc/dummy-master-1::gentoo USE="-static-libs" 0 KiB |
| 57 |
|
| 58 |
|
| 59 |
With the second version of DEPEND, emerge fails: |
| 60 |
# emerge -pv app-misc/dummy-master |
| 61 |
|
| 62 |
These are the packages that would be merged, in order: |
| 63 |
|
| 64 |
Calculating dependencies... done! |

emerge: there are no ebuilds built with USE flags to satisfy "=app-misc/dummy-slave-1[static-libs?]". |
| 67 |
!!! One of the following packages is required to complete your request: |
| 68 |
- app-misc/dummy-slave-1::gentoo (Missing IUSE: static-libs) |
| 69 |
(dependency required by "app-misc/dummy-master-1::gentoo" [ebuild]) |
| 70 |
(dependency required by "app-misc/dummy-master" [argument]) |
| 71 |
