RPM package of hplip 3.18.9 is difficult to install on CentOS 6 x86_64

[Alain Coron]

Installing the RPM provided for RHEL 6 (x86_64) leads to a problem related to libImageProcessor.so:

# yum localinstall hplip-3.18.9_rhel-6.0.x86_64.rpm
Loaded plugins: fastestmirror, refresh-packagekit

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

The libraries libImageProcessor.so is included within the package hplipfull.

I was able to force the installation with
  rpm -i --nodeps hplip-3.18.9_rhel-6.0.x86_64.rpm

However
# yum check dependencies
hplipfull-3.18.9-0.x86_64 has missing requires of libImageProcessor.so()(64bit)
hplipfull-3.18.9-0.x86_64 has missing requires of libImageProcessor.so(VERS_1.0)(64bit)
Error: check ['dependencies']
now complains about the missing requirements.

It would be nice, if one can avoid such problem.
