 This might be a little kludgey, but there's always `config-value'...
 ,----[ C-h f config-value RET ]

 `----
 See `config-value-file' for the symbols you can look up. 
But isn't using {early,late,last}-packages more robust than using
`config-value'?  By using {early,late,last}-packages we can rely on
XEmacs to sort out (non-)existent directories and don't have to fiddle
with those manually.  And we don't have to make any assumptions like
$prefix/lib/xemacs/site-packages if PACKAGE_PATH was not configured
which may break as soon as you decide to use a different default
location for packages.
