patch for systemtap-1.6.ebuild

systemtap-0.9 and above installs /usr/bin/dtrace, which is a python script.

1. this script starts out with #!/usr/bin/python, but it is incompatible with python3, and on Gentoo, /usr/bin/python can be python3; and
2. current systemtap ebuilds don't list a python dependency.

These problems can be resolved by inheriting the python eclass and using its python_convert_shebangs function.

My proposed patch for the systemtap-1.6 ebuild is attached.

I am usually using python 3 as my default python interpreter on a stable x86_64 system with some individual unstable packages. This bug fails the update to =dev-libs/glib-2.30.3 with

make[2]: Entering directory `/home/build/portage/dev-libs/glib-2.30.3/work/glib-2.30.3/glib'
  GEN    glib_probes.h
  GEN    glib_probes.o
  File "/usr/bin/dtrace", line 170
    print _("Usage ") + sys.argv[0] + " [--help] [-h | -G] [-C [-I<Path>]] -s File.d [-o <File>]"
SyntaxError: invalid syntax
  File "/usr/bin/dtrace", line 170
    print _("Usage ") + sys.argv[0] + " [--help] [-h | -G] [-C [-I<Path>]] -s File.d [-o <File>]"
SyntaxError: invalid syntax

As a workaround a temporary switch to python 2 resolves the issue, but this seems not a reasonable solution to me.

Always revbump when changing the installed state of a package.
Comment 8 Pacho Ramos gentoo-dev 2014-02-08 13:44:23 UTC
There were bumps after that commit and the fix was included there too
