# NOTE: The dev-python/python-fchksum RDEPEND is needed so that this python
#       provides the functionality expected from previous pythons.

# NOTE: python-fchksum is only a RDEPEND and not a DEPEND since we don't need
#       it to compile python. We just need to ensure that when we install
#       python, we definitely have fchksum support. - liquidx

# NOTE: changed RDEPEND to PDEPEND to resolve bug 88777. - kloeri
