Hi!
I'm trying to run the self tests for the pkgsrc package for lxml, currently at 5.3.0.
lxml itself seems to work fine AFAICT, but I can't get the self tests to runs.
I tried following the documented method from https://lxml.de/build.html but I get:
```
# python3.12 test.py
Traceback (most recent call last):
File "/scratch/textproc/py-lxml/work/lxml-5.3.0/test.py", line 620, in <module>
exitcode = main(sys.argv)
^^^^^^^^^^^^^^
File "/scratch/textproc/py-lxml/work/lxml-5.3.0/test.py", line 557, in main
test_cases = get_test_cases(test_files, cfg, cov=cov)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/scratch/textproc/py-lxml/work/lxml-5.3.0/test.py", line 260, in get_test_cases
module = import_module(file, cfg, cov=cov)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/scratch/textproc/py-lxml/work/lxml-5.3.0/test.py", line 201, in import_module
mod = __import__(modname)
^^^^^^^^^^^^^^^^^^^
File "/scratch/textproc/py-lxml/work/lxml-5.3.0/src/lxml/html/__init__.py", line 49, in <module>
from .. import etree
ImportError: cannot import name 'etree' from 'lxml' (/scratch/textproc/py-lxml/work/lxml-5.3.0/src/lxml/__init__.py)
```
so I guessed the PYTHONPATH was not set correctly and tried that:
```
# PYTHONPATH=build/lib.netbsd-10.99.11-amd64-cpython-312/ python3.12 test.py
```
with the same result.
I can import lxml.etree this way:
```
# PYTHONPATH=build/lib.netbsd-10.99.11-amd64-cpython-312/lxml/etree.so python3.12 -c "import lxml.etree"
Traceback (most recent call last):
File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'lxml'
# PYTHONPATH=build/lib.netbsd-10.99.11-amd64-cpython-312 python3.12 -c "import lxml.etree"
#
```
so I guess the test script doesn't honor it.
How can I run the tests?
Thanks,
Thomas
