Unable to rebuild packman packged chess program crafty for 11.3 from .src file

I tried to rebuild the packman packaged chess program ‘crafty’ (crafty-23.2-0.pm.1.1.src.rpm) on the most recent 11.3 release using this command:

rpmbuild --rebuild crafty-23.2-0.pm.1.1.src.rpm

and I ran into this error:

+ /bin/sh make_books
Creating bookfiles, this might take a moment.
Please be patient.
mv: cannot stat `book.bin': No such file or directory
error: Bad exit status from /var/tmp/rpm-tmp.itfBzR (%build)

RPM build errors:
    InstallSourcePackage at: psm.c:244: Header V3 DSA/SHA1 Signature, key ID 9a795806: NOKEY
    Bad exit status from /var/tmp/rpm-tmp.itfBzR (%build)

Is this a permissions error with the rpm being unable to create the book.bin ? or do I need to install and preposition that chess book library prior to building the rpm ?

Crafty is a dependency of xboard. I know I can ignore that xboard dependency needing crafty, but I also like the program crafty, so I wanted to also install it on my 11.3.
