tex-whizzytex @1.3.1 uses unnecessary pre-configure phase, which can cause a build failure

[cooljeanius (Eric Gallager)]

tex-whizzytex contains the following pre-configure block:

pre-configure {
                  system "open /Applications/Utilities/X11.app"
}

This led to the following error when I tried to install it:

--->  Configuring tex-whizzytex
DEBUG: Using compiler 'Mac OS X gcc 4.2'

LSOpenURLsWithRole() failed with error -10810 for the file /Applications/Utilities/X11.app.
Command failed: open /Applications/Utilities/X11.app
Exit code: 1

I'm assuming this is because LaunchServices probably can't open stuff for users that aren't actually currently logged in. Why does tex-whizzytex need to have X11 open to configure anyways? It seems unnecessary to me, at least without a comment to explain it...

btw I just looked up the LaunchServices error code in ​Apple's documentation for it; apparently it's an unknown error:

Result Code	Value	Description
kLSUnknownErr	-10810	An unknown error has occurred. Available in OS X v10.0 and later.

So that neither confirms nor denies my theory that it happened because it was being run by a non-logged-in user...
