info doesn't see the packages' info files
i had to manually create a `dir' file in .../xemacs-packages/info,
while, iicr, info used to generate a `dir' on the fly
the relevant variable looks ok to me:
(insert (pp Info-directory-list))
("/usr/local/lib/xemacs-21.5-b4/info/"
"/usr/local/lib/xemacs/xemacs-packages/info/"
"/usr/local/info"
"/usr/info"
"/usr/share/info")
