It seems to be a libtiff problem.

HylaFAX requires TIFFFaxBlackCodes, TIFFFaxBlackTable, TIFFFaxMainTable, TIFFFaxWhiteCodes, TIFFFaxWhiteTable, and _TIFFFax3fillrun

Stops working after update to libtiff (4.5.0-1)

Incompatible TIFF Library.

HylaFAX 6.0.7 requires TIFF software distribution versions 3.4 through
3.9. If you do not have up to date TIFF software on your system
then you can retrieve it from the location where you obtained this software.
The Home Page for version 3.5 and later is http://www.remotesensing.org/libtiff/

Unrecoverable error! Once you've corrected the problem rerun this script.

After downgrade libtiff (4.5.0-1 => 4.4.0-4) everything works again.
