Prob on Dreamhost

I created a vanilla app on Dreamhost in the hope to at least get
“Welcome” to display.

the URL I use is I do a
remapping to ~/ ghsrc/ when I add “public” to path i
get URL not found on this server. The app is under ~/ghsrc and
called I made chgs to environment…rb to point to prod.
Like I said I would expect to at least get the app to produce the
“welcome” form.

What am i doing wrong. Any help would be greratly appreciated.
