So I guess you want 4.0.26? Well, that's unstable, and the fact that you
just installed 4.1.14 suggests that your ACCEPT_KEYWORDS setting in
/etc/make.conf is set to stable (assuming x86 arch).

The best way to solve this would be by using a mixture of settings in
/etc/portage/package.mask and /etc/portage/package.keywords:

Assuming that the directory /etc/portage exists already (create it if not):

(as root)

echo ">=dev-db/mysql-4.1.14" >>/etc/portage/package.mask

to mask all versions of mysql greater than or equal to 4.1.14

and

echo "dev-db/mysql ~x86" >>/etc/portage/package.keywords

to unmask the unstable versions below the masked version (thus 4.0.26).

or you could unmask the specific version using

echo "=dev-dv/mysql-4.0.26 ~x86" >>/etc/portage/package.keywords

but be warned that this will not enable you to upgrade if 4.0.26 is
revised (4.0.26-r1) or upgraded (4.0.27), as those will still be masked
by the ~arch keword, as opposed to the previous command, which unmasks
all future unstable versions below 4.1.14.

If you use a different arch, change the "~x86" to your correct arch
(assuming that the version of mysql you want is available for that arch;
if it is not, adapt the above commands to the available versions that
you want to mask and unmask.

Then an emerge -uav world should come up with a [UD] for mysql (the
upgrade is a downgrade), and whatever else might need to be updated on
your system; if you don't want to emerge the other upgrades, just do an
emerge -uav mysql (but that will put mysql in your world file if it was
previously installed as a dependency of something else, and you may or
may not want mysql in your world file. But that's your choice).

Hope this helps.
