errors on RHEL 5.1 32bit Hplip install 2.8.9 on HP L7680

Good Morning,

I have on my hands an HP L7680 All in one printer. I use RHEL 5.1 32bit. The hplip packages that come with 5.1 does not have this printer listed. So I downloaded Hplip installer 2.8.9. Ran into the following error, and I am not sure why...

$ bash hplip-2.8.9.run
Creating directory hplip-2.8.9
Verifying archive integrity... All good.
Please choose the installation mode (a=automatic*, c=custom, q=quit) : a

Initializing. Please wait...

INSTALL MISSING OPTIONAL DEPENDENCIES
-------------------------------------
warning: There are 2 missing OPTIONAL dependencies.
note: Installation of dependencies requires an active internet connection.
warning: Missing OPTIONAL dependency for option 'gui': pyqt4 (PyQt 4- Qt interface for Python (for Qt version 4.x))
warning: This installer cannot install 'pyqt4' for your distro/OS and/or version.
warning: Missing REQUIRED dependency for option 'fax': python-dbus (python-dbus - Python bindings for dbus)
warning: This installer cannot install 'python-dbus' for your distro/OS and/or version.
warning: Option 'fax' has been turned off.

I plan on doing allot of scanning, printing and Faxing. What needs to be done to get this (faxing) to work? The missing dependencies above are on my system, (dbus-python-0.70-7.el5, qt4-4.2.1-1) which is why I am perplexed.

I tried to upgrade dbus to .80 (requires python 2.5x) but this would break our supported redhat configuration. Also on RHEL5.1 / CentOS5.1 there are alot of dependencies for this version of python (2.4.3)

Has this been tested on a Stock version of RHEL5.1 / RHEL5.2 ?
