py-test import failure

[gdt]

Problem description

I am updating the pkgsrc pkg for py-proj to 3.7.0. I do not have a clear memory of running tests before. In pkgsrc we invoked tests as 'make test' from the package directory, which invokes tests in a build-system-specific way in the build directory. This generally works, and it works with py-test which is normal.

Many packages load resources from the system rather than the build directory, making them not testable before install. As I generally don't try to fix those things, my normal practice is to install the new bits first and then test, so that test code that loads pyproj from /usr/pkg/lib/python3.12/site-packages/pyproj instead of the build dir will run as expected.

Then, I ran tests, and it failed to find _context. But, running the test program itself produced no errors, and I do see _context.so in the site-lib dir. ldd shows all its libs resolve ok.

Maybe it is trying to use the build tree? My build tree has _context.so and it looks normal:

> find . -name _context\*
./pyproj/_context.pxd
./pyproj/_context.pyi
./pyproj/_context.pyx
./pyproj/_context.c
