yum list installed httpd
does not show cwp-httpd-2.4.29-2.x86_64 as installed, i.e. it is not recognizing it as 'webserver'.
The OS is not even recognizing it as httpd, just
httpd -v
The latter aside the rpm semantics apparently provide for specification of the package and cwp-httpd seems to be missing 'webserver' as rpm descriptor and thence not being recognized by yum. In comparison the stock httpd ships with that descriptor.
