I replaced installed Hugs and ghc with the newest versions which I built myself. ghc works but hugs now exits with the message

Hugs.Prelude not found on current path: ".:{Home}/lib/hugs/packages/*:/usr/local/lib/hugs/packages/*"

FATAL ERROR: Unable to load prelude implementation

Where does hugs normally find the Hugs.Prelude file?

With these settings (which are the default),

/usr/local/lib/hugs/packages/hugsbase/Hugs/Prelude.hs

ls: /usr/local/lib/hugs/packages/hugsbase/Hugs/P*: Permission denied Thanks. Somehow directory /usr/local/lib/hugs had the x permissions removed from group and world which removed my access to Prelude. I restored the permissions and hugs now works again.
