To answer my own question:
This also happened without poudriere and PREFIX != LOCALBASE and
staging enabled.

I worked around the issue by putting this into Makefile

.if ${PREFIX} != ${LOCALBASE} && !defined(NO_STAGE)
PYSITEDIR=      ${PREFIX}${PYTHON_SITELIBDIR:S|^${LOCALBASE}||}
.else
PYSITEDIR=      ${PYTHON_SITELIBDIR}
.endif

and replacing ${PYTHON_SITELIBDIR} with ${PYSITEDIR}, e.g.

        ${ECHO} "Ice" > ${STAGEDIR}${PYSITEDIR}/Ice.pth
