I am certainly no Gentoo Wizard, but perhaps I can help a bit.

The file /etc/portage/package.mask tells portage what files to  
ignore. You can simply put the version that you want to use, preceded  
by the ">" sign, and portage will ignore any version greater than the  
one you specify. You need to put the full portage name of the  
package, for example:

 >dev-db/mysql-4.1.19

Would prevent portage from installing any version later than 4.1.19

An "=" instead of the ">"would prevent the installation of *any*  
version other than what you specified. This is useful whan something  
depends on a specific version of a dependency.

You need to append the "-r<n>" if the version you want to keep  
includes a revision level.

After you have made the entry in package.mask you should be able to  
just run:

emerge -avuDN world to get things the way you want them.

As I said I'm no wizard, so I may have some persnickety detail wrong  
here, but you get the basic idea.
