Bug#838572: clang-3.9: scan-view-3.9 does not find python modules

[Riccardo Magliocchetti]

Package: clang-3.9
Version: 1:3.9-1
Severity: normal

Hello,

scan-view-3.9 fails to find the needed python modules:

$ scan-view-3.9 scan-build-master/
Traceback (most recent call last):
  File "/usr/bin/scan-view-3.9", line 143, in <module>
    main()
  File "/usr/bin/scan-view-3.9", line 140, in main
    run(port, args, args.root)
  File "/usr/bin/scan-view-3.9", line 70, in run
    import ScanView
ImportError: No module named ScanView

the problem is that os.path.dirname(__file__) is /usr/bin and not
/usr/share/clang/scan-view-3.9/bin
as expected by the script.

A quick way to fix that is to hardcode the scan-view dir:

$ diff -u ../bin/scan-view.old ../bin/scan-view
