I'm filing this bug, because old style virtuals should be removed. This leads to an issue where I cannot replace app-crypt/mit-krb5 with app-crypt/heimdal and invoking preserved-rebuild to not break my install. Affected packages are at least app-crypt/mit-krb5 and app-crypt/heimdal. Tried quite a few things, nothing worked to solve this: [ebuild N ] app-crypt/heimdal-1.3.3-r1 USE="X berkdb hdb-ldap ipv6 otp pkinit ssl threads -afs -test" 5,610 kB [blocks B ] app-crypt/mit-krb5 ("virtual/krb5" is blocking app-crypt/heimdal-1.3.3-r1)
That's not going to work unfortunately: * You cannot even build one when the other is present without some surgery in the Makefiles (both provide same but incompatible header files). * Even if you do build, they provide the same libraries while following different -but similar- versioning schemes. There is no guarantee that it will work / will not clash in the future - even if it does work now. Probably a !! blocker for both packages is in order. Closing as CANTFIX.
