x11-themes/noia ebuilds have bad version numbers -- in the form of month-date-year *noia-120902 (09 Dec 02) *noia-111902 (19 Nov 02) Now, in this form, if a new ebuild will be made on January 1st, 2003 it will be something like noia-010103 -- that being a lower number than 120902, it won't be considered newer by portage and would not be upgraded with emerge -u. I suggest the versioning be changed to year-month-date.
Good catch, I'll fix this tonight.
I also noticed that x11-themes/conectiva-crystal has the same version number system.
fixed.
