According to the log the error happens at Command: dpkg-buildpackage --sanitize-env -us -uc -mamd64 / i386 Build Daemon (x86-ubc-01) <buildd_amd64-x86-ubc...@buildd.debian.org> -B -rfakeroot --changes-option=-O../tuxguitar_1.5.6+dfsg1-3_amd64-buildd.changes --buildinfo-option=-O../tuxguitar_1.5.6+dfsg1-3_amd64-buildd.buildinfo ... cat: debian/tuxguitar-alsa.poms: No such file or directory ...
The same error also happens on my laptop. After adding the link ln -s tuxguitar.poms debian/tuxguitar-alsa.poms dpkg-buildpackage works. Maybe this could be a workaround?
