[PyQt] Interbase QtSql driver

[Horst Herb]

I am am new to PyQt. I am using Ubuntu Linux "gutsy",  with PyQt4 version 4.3 
including the packaged python-qt4-sql.

According to the documentation, Interbase appears to be supported by Qt4's SQL 
module.
However, QSqlDatabase.drivers() lists only 
QPSQL7
QPSQL
QMYSQL3
QMYSQL
QSQLITE
QSQLITE2

1.) How can I activate / add the Interbase driver? I need it urgently for 
porting a legacy project

2.) What is the difference between QPSQL7 and QPSQL (I  se mostly Postgres 
8.2, so which driver should I use?)

I would be grateful for any answers.
Thanks,
Horst
