gpm fails to build from source in unstable on amd64. A build ends as
follows:

| if [ "/usr/bin/makeinfo" != "no" ]; then /usr/bin/makeinfo --no-split /<<PKGBUILDDIR>>/doc/gpm.texinfo -o /<<PKGBUILDDIR>>/doc/gpm.info; fi

| make: *** [debian/rules:8: binary] Error 2
| dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2

Since it built a day earlier, the cause very likely is the texinfo
upload. That totally leaves open the question where this needs fixing.
