py-qt6 problem: symbol not found

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

I've tried switching py-tortoisehg to py-qt6, and it builds fine, but
it fails to start (on NetBSD-current/amd64):

Traceback (most recent call last):
  File "/usr/pkg/bin/thg", line 163, in <module>

ImportError: /usr/pkg/lib/python3.11/site-packages/PyQt6/QtNetwork.abi3.so: Undefined PLT symbol "_ZN16QNetworkDatagram7destroyEP23QNetworkDatagramPrivate" (symnum = 1588)

The symbol is in /usr/pkg/qt6/lib/libQt6Network.so.6:

# nm /usr/pkg/qt6/lib/libQt6Network.so.6 | grep _ZN16QNetworkDatagram7destroyEP23QNetworkDatagramPrivate
0000000000086790 T _ZN16QNetworkDatagram7destroyEP23QNetworkDatagramPrivate

and the library is linked:

# ldd /usr/pkg/lib/python3.11/site-packages/PyQt6/QtNetwork.abi3.so
...
   -lQt6Network.6 => /usr/pkg/qt6/lib/libQt6Network.so.6
...

so I'm confused why it can't be resolved.

Any ideas?

Thanks,
 Thomas
