Steps to reproduce:
- add qt overlay
- do eix-update
- execute "eix -e dev-qt/qtcore"
all the packages from qt overlay are displayed under the 0 slot.
packages should be displayed under the appropriate slot (either 4 or 5).
Possible source of error:
SLOT variable for qt ebuilds in qt overlay are defined in eclasses.
The cache method "parse" and "parse*" uses only a heuristics and is known to be unlreliable.
Use a reliable (but slow) cache method like "ebuild" or "ebuild*" or, even better, produce correct metadata information with egencache.
See the section SPEEDUP of the eix manpage.
Sorry, I already realized that it is my bad setup.
