Background: TIFF G4 is also known as MMR.  HylaFAX doesn't support MMR 
in Class 1, and most modems don't support MMR in Class 2.  TIFF G4 is 
generally a tighter compression than TIFF G3, and so storing image 
files (particularly 200 dpi monochrome ones) in TIFF G4 is a good 
idea.  But, when you go to fax these TIFF G4 image files, HylaFAX must 
convert them to a format which it and/or the modem can use.  So, 
tiff2fax is called, which is really just a wrapper for tiffcp.  Thus, 
you see the tiffcp call in your error log.

The factor that "changed" between your RedHat 7.0 and 7.3 installations 
is with tiffcp giving an exit status of 9.  This is not a fatal error, 
but a warning status, and tiff2fax should continue rather than stop.

SO, you have a number of options.
   - implement the change to tiff2fax as noted
   - downgrade libtiff
   - stop using Windows/Kodak/Wang Imaging functions
