Yes, right - Fernando just pointed me to the reference - quoting him:

"As indicated here:

http://www.cosc.canterbury.ac.nz/greg.ewing/python/Pyrex/version/Doc/Manual/sharing.html#mozTocId559554

the search path for 'cimport foo' to find foo.pxd is the -I search
path of the compiler"

I don't have deep enough understanding of the differences to give a
reliable answer as to whether this is practical.  If it wasn't
practical, we could either standardize to Cython, or (less likely
surely) Pyrex, or have two sets of pxd files,
