problem with autoinstaller

[NightMan]

When I tried to upgrade my PSA through commandline autoinstaller
I gets following dependencies error

------------
Preparing for packages installation...

Installing packages
Installing php-pgsql-4.3.2-23.ent.i386.rpm
error: Failed dependencies:
php = 4.3.2-23.ent is needed by php-pgsql-4.3.2-23.ent
Not all required packages were installed.
Press <ENTER> to continue...
Select Plesk software source

how do I solve this? it seems I have PHP 4.3.2-30.ent installed already.
