Bug#1000950: python3-mshr: error processing line 3 of /usr/lib/python3/dist-packages/mshr.pth

[Andrius Merkys]

Package: python3-mshr
Version: 2019.2.0~git20200924.c27eb18+dfsg1-7

Hello,

When installing python3-mshr in clean sid chroot, the following message
is displayed multiple times:

"""
Error processing line 3 of /usr/lib/python3/dist-packages/mshr.pth:

  Traceback (most recent call last):
    File "/usr/lib/python3.9/site.py", line 175, in addpackage
      exec(line)
    File "<string>", line 1, in <module>
  FileNotFoundError: [Errno 2] No such file or directory:
'/usr/lib/petsc/include/petscconf.h'

Remainder of file ignored
"""

Despite the message, python3-mshr seems to install successfully.
Nevertheless the message gives an impression of installation failure [1].
