The following message is output at the end of emerging media-libs/ming-0.4.0_rc2: * Deprecation Warning: python_version() is deprecated and will be banned on 2010-07-01. * Use PYTHON() instead of python variable. Use python_get_*() instead of PYVER* variables. * The ebuild needs to be fixed. Please report a bug, if it has not been already reported. I am using sys-apps/portage-2.2_rc67 and dev-lang/python-2.6.4-r1.
Should be fixed in ming-0.4.3. Thanks for reporting this!
