this is normal (or if you prefer, this has been like that for 20 years or so).
Actually, there is no direct relationship between the line "required isl
version is" (just informative) and the line "*** This configuration is not
supported in the following directories..." (just information also). Actually,
I think that "not supported" here means just that those directories will not
be used.
