Description Kirk 2007-03-21 20:48:38 UTC
# emerge -av =dev-db/mysql-4.0.27-r1

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

Calculating dependencies -
!!! Multiple versions within a single package slot have been 
!!! pulled into the dependency graph:

('ebuild', '/', 'dev-db/mysql-5.0.26-r2', 'merge') pulled in by
  ('ebuild', '/', 'virtual/mysql-5.0', 'merge')

('ebuild', '/', 'dev-db/mysql-4.0.27-r1', 'merge') (no parents)

Reproducible: Always

Steps to Reproduce:
1.  Fresh install
2.  emerge -av =dev-db/mysql-4.0.27-r1

This will show us what's pulling it in: 

emerge -pt =dev-db/mysql-4.0.27-r1

Well, this is a portage issue...
nomerge      ] dev-db/mysql-4.0.27-r1  USE="-berkdb -big-tables -debug -embedded -minimal perl -raid (-selinux) ssl -static" 
[ebuild  N    ]  dev-perl/DBD-mysql-4.00.3  
[ebuild  N    ]   dev-perl/DBI-1.54  
[ebuild  N    ]    virtual/perl-Sys-Syslog-0.18  
[ebuild  N    ]    dev-perl/PlRPC-0.2018  
[ebuild  N    ]     dev-perl/Net-Daemon-0.39  
[ebuild  N    ]   virtual/mysql-5.0  
[ebuild  N    ] dev-db/mysql-4.0.27-r1  USE="-berkdb -big-tables -debug -embedded -minimal perl -raid (-selinux) ssl -static" 
[nomerge      ]  dev-perl/DBD-mysql-4.00.3  
[nomerge      ]   virtual/mysql-5.0  
[ebuild  N    ]    dev-db/mysql-5.0.34  USE="-berkdb -big-tables -cluster -debug -embedded -extraengine -latin1 -max-idx-128 -minimal perl (-selinux) ssl -static" 
[ebuild  N    ]     dev-db/mysql-init-scripts-1.2  

$ USE="-*" emerge -pt =dev-db/mysql-4.0.27-r1

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

Calculating dependencies... done!
[ebuild  N    ] dev-db/mysql-4.0.27-r1  USE="-berkdb -big-tables -debug -embedded -minimal -perl -raid (-selinux) -ssl -static" 
[ebuild  N    ]  dev-db/mysql-init-scripts-1.2  

dev-perl/DBD-mysql PDEPENDs on virtual/mysql; mysql.eclass PDEPENDs on dev-perl/DBD-mysql w/ USE=perl. Anyway, pretty much anything that depends on virtual/mysql and gets into depgraph will cause this.
Comment 3 Zac Medico gentoo-dev 2007-03-22 01:28:54 UTC
Yes, this is a very long standing bug.  If you want mysql-4 then you'll have to mask mysql-5:

echo ">=virtual/mysql-5" >> /etc/portage/package.mask

You also have to mask >=dev-db/mysql-5 if dev-db/mysql is in your world file or something depends on it, otherwise you'll get a similar error when you update your system.

Even if bug 1343 is fixed, there's still no support for a versioned atom in the world file.  We should have support for something like that in the near future though (bug 144480).
