Gnumeric: no help

["Paul Smith" <phhs80@xxxxxxxxx>]

Dear All

I have just installed Gnumeric with yum, but when I try to access to
the help (by pressing key F1), I get the error:

"Could not load the document

The Uniform Resource Identifier
'file:///usr/share/gnumeric/1.6.3/doc/C/gnumeric.xml' is invalid or
does not point to an actual file.'

Furthermore,

$ dir /usr/share/gnumeric/1.6.3/doc/C/gnumeric.xml
dir: /usr/share/gnumeric/1.6.3/doc/C/gnumeric.xml: No such file or directory
$

Any ideas?

Thanks in advance,

Paul
