Steps to Reproduce

Getting this error when building https://github.com/bempp/ndelement, eg in the yanked pypi releases (https://pypi.org/project/ndelement/0.1.0.dev2/). Can get error locally by running:

pip install target/wheels/ndelement-....whl
python -c "import ndelemement"

For future reference, the full error is

Traceback (most recent call last):

OSError: cannot load library '/usr/local/lib/python3.12/site-packages/ndelement/_ndelementrs/_ndelementrs.so': libblas-babdd0d2.so.3: cannot open shared object file: No such file or directory

the problem is that the rpath is computed wrong:

root@5bc794e9f041:~# patchelf --print-rpath /usr/local/lib/python3.12/site-packages/ndelement/_ndelementrs/_ndelementrs.so
$ORIGIN/../ndelement.libs

should be $ORIGIN/../../ndelement.libs.
