Comment 5 for bug 413928

According to rmadison, the only automake1.10 package is the source:
$ rmadison -u ubuntu automake1.10
automake1.10 | 1:1.10.1-2 | hardy | source
automake1.10 | 1:1.10.1-3 | intrepid | source
automake1.10 | 1:1.10.2-0ubuntu3 | jaunty | source
automake1.10 | 1:1.10.2-0ubuntu3.09.04 | jaunty-proposed | source
automake1.10 | 1:1.10.2-1ubuntu2 | karmic | source

$ rmadison -u ubuntu automake
  automake | 1:1.4-p6-9 | dapper | source
  automake | 1:1.4-p6-12 | hardy | source
  automake | 1:1.4-p6-13 | intrepid | source
  automake | 1:1.4-p6-13 | jaunty | source
  automake | 1:1.4-p6-13 | karmic | source
  automake | 1:1.10.1-2 | hardy | all
  automake | 1:1.10.1-3 | intrepid | all
  automake | 1:1.10.2-0ubuntu3 | jaunty | all
  automake | 1:1.10.2-0ubuntu3.09.04 | jaunty-proposed | all
  automake | 1:1.11-1 | karmic | all

But I wonder why the debian system builds them:
https://buildd.debian.org/pkg.cgi?pkg=dbus-c%2b%2b

Shouldn't the ppa build system and the debian build system be compatible?
