I'm not sure how I was doing this, or how I got past the problem, but
ISTR I had a:
CC="gcc -L/usr/local/cpython-2.7/lib -Wl,-rpath
-Wl,/usr/local/cpython-2.7/lib" in my
build shell script, and when I moved those options to a $LDFLAGS,
things started working better.

Yes, at /usr/bin/python3, and at /usr/local/cpython-3.[01234].

Nod.  I also have the py2cairo tarball listed below.  My script
autodetects the python major version and chooses accordingly.
