[Debian-med-packaging] Bug#745782: smalt: FTBFS when not building -examples: Directory nonexistent

[Aaron M. Ucko]

Source: smalt
Version: 0.7.6-1
Severity: serious
Justification: fails to build from source

Builds of smalt covering only its architecture-dependent binary
packages (as on the autobuilders) have been failing:

  # fix path to smalt executable in examples
  for py in `ls test/*.py` ; do \
  	    sed 's#PROGNAM = "../src/smalt"#PROGNAM = "/usr/bin/smalt"#' ${py} > debian/smalt-examples/usr/share/doc/smalt/${py} ; \
  	done
  /bin/sh: 2: cannot create debian/smalt-examples/usr/share/doc/smalt/test/bam_cigar_test.py: Directory nonexistent
  ...
  make[1]: *** [override_dh_install] Error 2

As with staden-io-lib (thanks for the quick fix there!), please
conditionalize this operation on the existence of debian/smalt-examples.

Thanks!
