Bugzilla Bug 257009

(Sorry if this is a dupe, i looked...honest =P )

In this situation:

%% sudo emerge -av postfix

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild  N    ] net-mail/mailwrapper-0.2.1  0 kB                                
[ebuild  N    ] mail-mta/postfix-2.5.5  USE="dovecot-sasl ldap mailwrapper
mysql sasl ssl -cdb -hardened -ipv6 -mbox -nis -pam -postgres (-selinux) -vda"
0 kB  
[blocks B     ] mail-mta/exim ("virtual/mta" is blocking mail-mta/exim-4.69)

Total: 2 packages (2 new), Size of downloads: 0 kB
Conflict: 1 block (1 unsatisfied)                                               

 * Error: The above package list contains packages which cannot be              
 * installed at the same time on the same system.

It would be convienient if portage prompted to unmerge the offender. As in,
"blocker $foo exists in the world file, would you like to unmerge this before
continuing? (yes/no)"

This makes sense because I invoked emerge with -a, so it should ask me. Also, I
explicitly called for the mutual blocker to be installed, it didn't get pulled
in by something else.

Thanks for consideration. ;)
