1) Nit: DEPENDENCY_SCRIPT please.
2) Don't use current work directory, this should be os.path.dirname(__file__).

+
+try:
+    subprocess.check_call(["python", DEPENDECY_SCRIPT])

[Wladimir Palant, 2014/12/17 14:29:32]

Only call this if the script actually exists please - this file should be the
same everywhere, and we don't want any warnings if there are no dependencies.

+except subprocess.CalledProcessError as e:
+    print >>sys.stderr, str(e)+'\n'

[Wladimir Palant, 2014/12/17 14:29:32]

print will automatically add a newline, no need to do this. Also, e doesn't need
to be converted to string explicitly:

  print >>sys.stderr, e

+    print >>sys.stderr,"Failed to ensure dependencies being up-to-date!"+'\n'

[Wladimir Palant, 2014/12/17 14:29:32]

Style nit: space after comma please.

Newline is unnecessary here as well.
