Tests fail with out-of-source build

$ python3.7 testsuite/test_cint.py
Traceback (most recent call last):
  File "testsuite/test_cint.py", line 16, in <module>
    _cint = numpy.ctypeslib.load_library('libcint', os.path.abspath(os.path.join(__file__, '../../build')))
  File "/usr/local/lib/python3.7/site-packages/numpy/ctypeslib.py", line 157, in load_library
    raise OSError("no file with expected extension")
OSError: no file with expected extension

My build is in /usr/ports/science/libcint/work/.build/ as set by the FreeBSD ports framework.

You may need to change this line to

_cint = numpy.ctypeslib.load_library('libcint', '/usr/ports/science/libcint/work/.build')

Now tests work, thanks!
