I don't really understand the suggestion here.  --print-datadir prints
whatever is coming from options passed to ./configure, typically
--prefix.  And this is usually an absolute path, so it is actually
fairly unconventional for --print-datadir to return a relative path.

Can you give me details on how you reached that state?
