qt4-mac and qt4-mac-sqlite3-plugin create trouble

[mkae (Marko Käning)]

There are two intertwined scenarios when I ran into trouble with qt4-mac and qt4-mac-sqlite3-plugin:

---

1) Developing the update of skrooge to version 1.4.0:

At first I hadn't qt4-mac-sqlite3-plugin installed during upgrading port skrooge from 1.3.3 to 1.4.0 and here is what I got when I tried to start the app:

QSqlDatabase: QSQLITE driver not loaded
QSqlDatabase: available drivers: QSQLITE3 QMYSQL3 QMYSQL
QSqlQuery::exec: database not open
##WARNING: PRAGMA table_info( doctransaction );
##         returns :Driver not loaded Driver not loaded

Please notice that QSQLITE3 is already listed as available driver!!! BUT, as you can see above it cannot be used. Weird, isn't it?
​https://bugs.kde.org/show_bug.cgi?id=312668

This problem disappeared when I installed port qt4-mac-sqlite3-plugin - which I then added as a necessary dependency for skrooge!

Nice, but strange, since it caused my 2nd problem...

2) Running tests of kmymoney4-devel with qt4-mac-sqlite3-plugin installed

$ git clone git://anongit.kde.org/kmymoney
$
$ cd kmymoney; mkdir build; cd build; cmake ..   # this of course only succeeds if kmymoney-devel and all its deps are installed in MacPorts already
$
$ ccmake ..    # enable test by setting KDE4_BUILD_TESTS to ON
$
$ make
$
$ /opt/macports-test/bin/ctest --force-new-ctest-process -R databasemgrtest -V

The following tests FAILED:
	 20 - kmymoney-mymoneydatabasemgrtest (OTHER_FAULT)
Errors while running CTest

I haven't tried to check in detail what caused the errors in testAddTransactions() up to now...

However, if I now deactivate qt4-mac-sqlite3-plugin the test is running fine!

This is what I have installed:

$ port installed qt4-mac*
The following ports are currently installed:
  qt4-mac @4.8.4_2+debug+quartz (active)
  qt4-mac-mysql5-plugin @4.8.4_0+debug (active)
  qt4-mac-mysql55-plugin @4.8.4_0 (active)
  qt4-mac-sqlite3-plugin @4.8.4_0

What am I missing?

What can be done about this seemingly complex situation?
