Problem with "make install": Missing file amaya/Amaya?

The file Thot/amaya/Makefile.in has changed thus:

in 1.3b, it read (lines 28-29):

AMAYAFILES= HTML.STR HTML.conf HTML.trans HTML.en HTML.fr\
           HTML*.PRS HTML*.TRA

now in 1.4a, it reads (lines 33-34):

AMAYAFILES= HTML.STR HTML.conf HTML.trans HTML.en HTML.fr\
           HTML*.PRS HTML*.TRA Amaya

This file Amaya does not exist when I come to do a "make install".  Should
there be such a file there, or is the Makefile.in erroneous?

Thanks,

Ewan Mellor.
