[mythtv-users] QT MySql error (it looks like qtmysql is installed)

Hi, I run mythtv on a gentoo system.  I recently updated to the newest 
version available on portage:

~: mythbackend --version
Library API version: 0.20.20060828-3
Source code version: Unknown
Options compiled in:
 linux release using_v4l using_oss using_alsa using_ivtv using_lirc 
using_joystick_menu using_x11 using_xv using_xrandr using_opengl_vsync 
using_opengl using_frontend using_backend using_bindings_perl

When doing so mythbackend stopped starting.  The strange thing is, I did 
the exact same emerge on another system that I run myth on, and it works 
fine.  The error I get is:

~: mythbackend
2007-01-02 14:28:16.153 Using runtime prefix = /usr
QSqlDatabase: QMYSQL3 driver not loaded
QSqlDatabase: available drivers:
2007-01-02 14:28:16.168 New DB connection, total: 1

No error type from QSqlError?  Strange...
2007-01-02 14:28:16.290 Failed to init MythContext, exiting.

I can't figure out why qmysql3 driver would get lost, the driver is 
still there as far as I can tell:
~: locate mysql | grep -i qt

This list basically matches the list on my other system where I'm not 
experiencing this error.

Other info:
~: mysql --version
mysql  Ver 14.12 Distrib 5.0.26, for pc-linux-gnu (i686) using readline 5.1

*  x11-libs/qt
      Latest version available: 4.1.4-r2
      Latest version installed: 4.1.4-r2

There's no package qt-mysql, but since I've never had this problem 
before, I assume that is covered by having mysql in USE keywords when 
building qt (which I have).

Again I didn't experience this problem with a 2 month old build, but 
experience it with this newest version.  Any help would be greatly
