? In both cases (`PATH` as well as `LD_LIBRARY_PATH`), directories get
'''pre'''pended (provided they exist).
On Unices, `libpython-*.so*` is in `$SAGE_LOCAL/{lib,lib32,lib64}/`, so
can be found along `$LD_LIBRARY_PATH`.
If Cygwin's `dlopen()` conforms to POSIX (it probably does), it doesn't
use `PATH` but `LD_LIBRARY_PATH` (if set), unless an absolute path was
given in the filename argument.
