It's going to use the same libc as python, so first of all check which
libc your python interpreter is actually linked to. Maybe your custom
build didn't do quite what you wanted.

ldd `which python` # or something like that

Once you've convinced yourself that python has the correct libc, you
could try building tensorflow from source rather than installing the

Maybe something in here helps:
