Glib and Gtk2 do a lot of extra work in their XS bootstrapping code;  
the normal DynaLoader bootstrapping process calls the boot symbol for  
the package with the same name as the one you've "use"d, and in Glib  
and Gtk2, those then call all of the other boot symbols for the rest of  
the extensions.  See lines 285 to 319 of  
http://cvs.sourceforge.net/viewcvs.py/gtk2-perl/gtk2-perl-xs/Glib/ 
Glib.xs?annotate=1.34 , for example; the GPERL_CALL_BOOT() lines  
actually invoke the code in the BOOT: sections of the corresponding XS  
files.

If i understand PAR correctly, it actually packages the necessary  
modules and libraries for an XS extension in the PAR file, and extracts  
them to a temp dir so they can be loaded normally.  In that case, i  
*really* don't understand why it wouldn't work.

Worse yet, it appears to do only partial bootstrapping of the Glib  
module.  The error message listed in whitewindow's post is something  
from libgobject, complaining that it was not properly initialized --  
however, GLib's initialization happens the first time you load Glib  
into your script.

Also, it may be worth pointing out to the PAR folks that this same  
script works flawlessly on linux (i tried it a few weeks ago and had no  
problems with it).  If they have questions about gtk2-perl internals,  
point them to me.
