The net-nds/openldap-2.1.21 depends on >=db-4.0 while it will only build with db-4.1 as the configure script blocks lower versions. Probably the dependency needs to be fixed.
amd64 is the only arch in the KEYWORDS of either db-4.1.24 or 4.1.25... :( does it need testing yet to even get a ~ or is there some other reason?
openldap-2.1.22 has been added to portage with the dependancy changed to >=db-4.1 and other fixes. Please test.
There are still some packages which break on >=db-4.0, so it is still masked. I'm confident though, that the with respect to db this package is now correct. I'll try it out later (possibly tomorow)
restoring old statuses.
