There's not a variable, but you could use the getcwd() function
somewhere to figure out what it is.  Or just run PmWiki with
?action=phpinfo, and then look at the DOCUMENT_ROOT or
SCRIPT_FILENAME entries in the PHP Variables to learn what the
absolute path is.

If the templates are being loaded but not the stylesheets, that
indicates that $SkinLibDirs itself is probably okay but there's
something wrong with $FarmPubDirUrl.  (You are setting $FarmPubDirUrl
*before* setting $SkinLibDirs, yes?)

You originally wrote "...with what will i need to replace $siteroot?"
and my response was "You might try replacing $SiteRoot with an
absolute path to the farm/pub/skins directory."  As you mentioned
in another email, you were just using $SiteRoot as a placeholder
to demonstrate what is missing; I was using $SiteRoot in exactly the
same sense, and not as a real variable that is being set somewhere
(although you could certainly do that).

The key question to resolving this is to know if the page is
being displayed with or without the skin template.  If you're
getting a "skin not found" error, that indicates a problem with
the filesystem path (the key).  If the page is displaying
but none of the .css and/or .gif images are loading, that's
a problem with the url portion and/or $FarmPubDirUrl.
