This is correct..  That's because load-file-path requires a full path.
It doesn't perform any variable expansion, and '~' is shell syntax.
So this isn't at all surprising.

There may be a guile function to expand the path but I don't know what
it may be offhand.

Regardless, this is completely unrelated to Phil's sugggestion and
should not have been a reply to his message.

Thanks,
