Why can't I install LMS 7.9.2 on Fedora 28?

When I try, I get this

# rpm -i ./logitechmediaserver-7.9.2-0.1.1550612824.noarch.rpm
error: Failed dependencies:
perl >= 5.8.8 is needed by logitechmediaserver-7.9.2-0.1.1550612824.noarch

...but I have perl 5.26.3.

I'm sure I have this version running on another F28 server - am I missing some magic incantation here?

Thanks in advance for any help...

Jon.
