	I think this is the second error I got when
trying to build a frontend, all those months ago.
(first one was that -O3 was causing virtual thunk
  errors due to stripping out the moc_* methods).


I asked:

> QSqlDatabase: available drivers:
> QSqlDatabase: QMYSQL3 driver not loaded
> QSqlDatabase: available drivers:

and J. Donavan Stanley replied:

	Basically, when you configure Qt, you need to
make sure that it is something like:

configure -system-zlib -thread -stl -freetype -qvfb -plugin-sql-mysql \
-I/usr/local/mysql-max-4.0.20-apple-darwin6.8-powerpc/include \
-L/usr/local/mysql-max-4.0.20-apple-darwin6.8-powerpc/lib

(note the -plugin-sql-mysql).

	If it was in there, then that isn't it, and it probably
means something strange with LD_LIBRARY_PATH or QTDIR.

(libqt-mt.dylib needs to open something like
  $QTDIR/plugins/sqldrivers/libsqlmysql.dylib)


	Bonne chance.
