Plesk 8 Installation Error

[Xploreweb.com]

I am installing plesk 8 on RHEL 4 x86-64bit ES Update 3, but i'm getting this installation error during the installation. This error occured after i got the packages list where i did select all packages from plesk. Clicked 'N' for next page and the following error occured. I have no clue how i can fix it. I quote literally:

Reading system installed packages...done.
Download file plesk-8.0.0-rhel4-x86_64hdr.gz: 41%..90%..100% done
Download file plesk-8.0.0-rhel4-x86_64hdr.gz: 26%..51%..76%..100% done
Resolve components
ERROR: ERROR: Package resolver can't found solution for this packages set.
ERROR: Installation Failed

I succesfully installed plesk before on rhel 4 es 64 bit Initial release. Now im having this error. Thank you in advance for all your help and concerns.

Update:

Postgresql seemed to be the problem.. I unchecked that during installation, and worked fine..

I still didnt trace why postgresql, because i didnt have it installed only one LIB which is used by another app. So hard to uninstall..
