The runestone in question is the Karlevi Stone on Öland
and the verse is commemorating the otherwise obscure Sibbi the Good:

"This stone is placed in memory of Sibbi the Good, Foldan's son, and his retainer placed on Öland this memorial to honour the dead.

Not content with setting up a permanent memorial to his leader that still stands a millennium later, the unnamed follower also commissioned (or perhaps even composed) a memorial verse to Sibbi, and this verse forns the second part of the inscription

"Fulkin : likr : hins : FulkÞu : flaistr (:)* uisi : Þat * maistar * taiÞir : tulka ÞruÞar : traukr : i : Þaimsi * huki : munat : raiÞ : uiÞur : raÞa : ruk : starkr * i *: tanmarku --(n)tils : iarmun ** kruntar : urkron-tari : lonti"

Folginn liggr hinns fylgðu,
flestr vissi pat, mestar
dæðir dolga Þrúðar
draugr í Þessu haugi.
Munat reið- Viður raða
rógstarkr í Danmórku
Endils jormungrundar
ørgrandari landi.

Hidden in this mound lies one, an executor of the goddess of battles [valkyrie~warior], whom the greatest deeds followed (most knew that). No strife-strong god of the wagon of Endill's wide ground [sea~ship~captain] will rule land in Denmark more faultlessly."

This is from 'Ships and Men in the Late Vikingage'
by Judith Jesch.
