glib-2* vs. glib2* in gnome_upgrade.sh

[Frederick Joseph Ross]

I'm not sure if this is correct or no, but with a CVSup'd ports tree, I 
had to go in and change glib-2* to glib2* on line 64 to make the script 
carry through.  Otherwise it complained about not being able to find said 
port.

Otherwise, all has gone quite smoothly.  Well done packaging this!
