[Yhc] Yhc Scons and chmod

[Neil Mitchell]

Hi

I'm trying to install Yhc on venice, Matt originally installed it, I
did darcs pull scons. I have permissions to do stuff to the yhc
directory, but not permission to do a chmod, as the setup script seems
to do:

Warning: The module PreludeBuiltin is called Prelude in its interface
file (/grp/haskell/yhc/src/packages/yhc-base-1.0/PreludeBuiltin.hi)

    os.chmod(dst, mode)
OSError: [Errno 1] Operation not permitted:
'src/packages/yhc-base-1.0/Prelude.hi'
scons: building terminated because of errors.

So the question is:

1) Does the setup really need to do a chmod

2) If the chmod fails, what can't we do? Could we perhaps limp along
to the end anyway.

Thanks
