Hello,

builldd of ia64 was trying to execute override_dh_auto_build-indep
rules during arch-only build.
But because of absent build-depends-indep packages, it failed [1] ...

====================
Running script yadeSphinx.py
Traceback (most recent call last):
  File "/build/buildd-yade_0.80.0-2-ia64-M5xwAf/yade-0.80.0/debian/inst/bin/yade",
line 172, in runScript
    execfile(script,globals())
  File "yadeSphinx.py", line 202, in <module>
    import sphinx,sys,shutil
ImportError: No module named sphinx
[[ ^L clears screen, ^U kills line. F8 plot. ]]

  [0;34m Yade [  [1;34m 1  [0;34m ]:   [0m
Do you really want to exit ([y]/n)?

/bin/sh: 1: xelatex: not found
