     AIPS cannot handle such names.  Itbreaks at the dot and there are
really too many characters.  Edit $AIPS_ROOT files HOSTS.LIST (to add
LOCALHOST), LOGIN.SH and LOGIN.CSH to change LAPTOP to YES.  Then edit
$AIPS_ROOT/DA00/DADEVS.LIST to add LOCALHOST_n areas to match the ones
you already have for marvelcube.local.  In that area
   ln -s MARVELCUBE.LOCAL LOCALHOST
or whatever aips called the machine before and wherever you put the
data make 
   ln -s  MARVELCUBE.LOCAL_n LOCALHOST_n
link files.

The source LOGIN.CSH  or . LOGIN.SH and
echo $HOST
which should say LOCALHOST.  This should then work.
