[Comment 1 James Browning 2018-09-11 20:13:26 UTC]

I am not seeing it on my system. The pylib files should be in the directory /usr/lib64/pythonX.Y/site-packages/ntp/ where X.Y has the values of (for your box 2.7 and 3.6) It might also generate errors if /usr/lib is not a symlink to lib64

[Comment 2 Gary E. Miller 2018-09-11 21:01:59 UTC]

I see your PYTHON_TARGETS must be set to "python2_7 python3_5 python3_6"

Which is your live Python?  Find out one of this way:

$ python -V
Python 2.7.15

The emerge should have installed for all three Python versions.  The file would be here:

$ ls /usr/lib64/pyt*/site-packages/ntp -d
/usr/lib64/python2.7/site-packages/ntp
/usr/lib64/python3.5/site-packages/ntp
/usr/lib64/python3.6/site-packages/ntp
```

And, as the emerge asked, check your PYTHONPATH:

$ echo $PYTHONPATH
/usr/lib64/python2.7/site-packagages

[Comment 3 Gary E. Miller 2018-09-11 21:37:44 UTC]

Confirmed nroken install.

I just installed the ebuild.

In my make.conf:

PYTHON_SINGLE_TARGET="python3_5"
PYTHON_TARGETS="python2_7 python3_4 python3_5 python3_6"

The emerge only installed some different files for different python versions:

ntpc.so for only Python 2.7:

# ls  /usr/lib64/python*/site-packages/ntp/ntpc.so
/usr/lib64/python2.7/site-packages/ntp/ntpc.so

But it did create all the install directories:

$ ls -l /usr/lib64/python*/site-packages/ntp/ -d
/usr/lib64/python2.7/site-packages/ntp/
/usr/lib64/python3.4/site-packages/ntp/
/usr/lib64/python3.5/site-packages/ntp/
/usr/lib64/python3.6/site-packages/ntp/

It installed ntpdc.so with odd names for the other versions:

# ls  /usr/lib64/python*/site-packages/ntp/ntpc*
/usr/lib64/python2.7/site-packages/ntp/ntpc.so
/usr/lib64/python3.4/site-packages/ntp/ntpc.cpython-34m.so
/usr/lib64/python3.5/site-packages/ntp/ntpc.cpython-35m-x86_64-linux-gnu.so
/usr/lib64/python3.6/site-packages/ntp/ntpc.cpython-36m-x86_64-linux-gnu.so


Clearly broken.

[Comment 4 Gary E. Miller 2018-09-11 21:41:21 UTC]

You can get ntpmon to work this way:

# eselect python list
Python interpreters, in order of preference:
  [1]   python3.6
  [2]   python2.7


# /usr/bin/ntpmon
ntpmon: can't find Python NTP library -- check PYTHONPATH.
dynamic module does not define module export function (PyInit_ntpc)


# eselect python set 2

# /usr/bin/ntpmon

[works]

So the ebuild install of the python libs is broken.
