Bug#793348: sfepy: FTBFS: Permission denied: '/sbuild-nonexistent'

[Aaron M. Ucko]

Source: sfepy
Version: 2015.1-1
Severity: important

Builds of sfepy failed everywhere but the Hurd (whose autobuilder
evidently uses a slightly different setup):

  Making output directory...
  Running Sphinx v1.2.3
  WARNING: extension 'ipython_console_highlighting' has no setup() function; is it really a Sphinx extension module?
  
  Exception occurred:
    File "/usr/lib/python2.7/os.py", line 157, in makedirs
      mkdir(name, mode)
  OSError: [Errno 13] Permission denied: '/sbuild-nonexistent'

/sbuild-nonexistent is the HOME value most autobuilders set because
packages frankly have no business with actual home directories.  If
sphinx-build needs to access HOME, please arrange to set it to a
specially created directory within the package's build tree.

Could you please take a look?

Thanks!
