You got a PHP error? What error?
Your second version is the correct one -- i.e., it should be
with the double quotes.

No, they're totally different. The key is to recognize the difference
between working with urls and files on disk. The include() statements
are used to include other files (on disk) into the currently running
PmWiki script. Thus they require filename paths.
The $ScriptUrl and $PubDirUrl variables are used to tell a *browser*,
connecting via the webserver, how to execute the pmwiki script
($ScriptDirUrl) and the base url for getting files from PmWiki's
pub/ directory ($PubDirUrl). Note that a browser needs a
url (http://www.example.com/pmwiki/pub) while an include statement
requires a file path ($FarmD/scripts/something.php).
Also note that a browser never accesses the files in scripts/ or
the cookbook/ directly, but always goes through the pmwiki.php
script, as specified by $ScriptUrl.

$ScriptUrl is the url that you want people's browsers to use when
accessing PmWiki, either as a field or farm. It's used whenever
PmWiki needs to generate a link to another PmWiki page or action.
PmWiki is usually fairly good about "guessing" the correct value for
$ScriptUrl on its own, but sometimes an admin needs to set it explicitly
because of url manipulations by the webserver (e.g., CleanUrls, mod_rewrite,
errors in the PHP configuration, etc.).
If the system works without setting $ScriptUrl and you're happy with
the results, then don't change it. :-)
