Hi, I've tried to track down the problem this night. The 'bootstrap' file is not executable and this make the boot target of debian/rules fail ungracefully.
After running debian/rules boot, the package builds fine. The problem is that debian/rules clean is not doing his work and therefore trying to build the package again led to "unrepresentable changes to source"; perhaps Makefile.in is not generated correctly, I don't know. Here you can find a full pbuilder log of a successful build: http://people.debian.org/~ema/snacc_1.3bbn-6 HTH. ciao, ema -- Questo è il domani di cui ti preoccupavi ieri. E ora sai perché.
