Installation af MDB2_Driver_mssql-1.5.0b3.tgz til PHP/pear

Hjælp

Jeg er helt ny til PHP, men håber at en venlig sjæl kan hjælpe mig alligevel.

Jeg er igang med installere Apache, MySQL og PHP / pear.

OS: Windows 2008 R2
Apache version 2.2.22 er installeret i C:\Apache [testet ok]
MySQL version 5.5.27 er installeret i C:\MySQL [testet ok]
PHP version 5.4.6 er installeret i C:\PHP [testet ok]


Problemet opstår når jeg forsøger at installere MDB2 driveren til pear (MDB2_Driver_mssql-1.5.0b3.tgz).

Trin 1 er ok:
c:\PHP>pear install MDB2-2.5.0b3.tgz
Package "pear.php.net/MDB2" dependency "pear.php.net/PEAR" has no releases
install ok: channel://pear.php.net/MDB2-2.5.0b3
MDB2: Optional feature fbsql available (Frontbase SQL driver for MDB2)
MDB2: Optional feature ibase available (Interbase/Firebird driver for MDB2)
MDB2: Optional feature mssql available (MS SQL Server driver for MDB2)
MDB2: Optional feature mysql available (MySQL driver for MDB2)
MDB2: Optional feature mysqli available (MySQLi driver for MDB2)
MDB2: Optional feature oci8 available (Oracle driver for MDB2)
MDB2: Optional feature odbc available (ODBC driver for MDB2)
MDB2: Optional feature pgsql available (PostgreSQL driver for MDB2)
MDB2: Optional feature querysim available (Querysim driver for MDB2)
MDB2: Optional feature sqlite available (SQLite2 driver for MDB2)
MDB2: Optional feature sqlsrv available (MS SQL Server driver for MDB2)
MDB2: To install optional features use "pear install pear/MDB2#featurename"

Trin 2 fejler konstant:
c:\PHP>pear install MDB2_Driver_mssql-1.5.0b3.tgz
Package "pear.php.net/MDB2_Driver_mssql" dependency "pear.php.net/MDB2" has no r
eleases
pear/MDB2_Driver_mssql requires PHP extension "mssql"
No valid packages found
install failed

Hvad overser jeg ?

NB: kan godt kører phpinfo.php og check_pear.php

På forhånd tak for hjælpen.
