After the recent update from hylafax 6.0.6 to hylafax+ 5.5.5 (a good move,
BTW!), the hylafax+-client cannot be installed standalone anymore. 

Since the server installs cron jobs, that results in complains by mail similar
to:

HylaFAX Usage Report

FATAL ERROR: /var/spool/hylafax/etc/setup.cache is missing!

The file /var/spool/hylafax/etc/setup.cache is not present.  This
probably means the machine has not been setup using the faxsetup(8C)
command.  Read the documentation on setting up HylaFAX before you
startup a server system.

An attempt to uninstal the server results in:

$ rpm -e hylafax+
error: Failed dependencies:
        libfaxutil.so.5.5.5()(64bit) is needed by (installed)
hylafax+-client-5.5.5-2.1.x86_64

Please relocate the libfaxutil into its own package.

Thanks.
