I forgot to mention that, having installed Glib-Object-Intropsection-0.042 
(even though the test libraries had not been built), I then get the 
following disconcerting output if I require() the module:

C:\>perl -le "require Glib::Object::Introspection; print 'loaded';"
Too late to run INIT block at 
C:/MinGW/perl524_64int/site/lib/Glib/Object/Introspection.pm line 257.
loaded

Is there an issue in that ?

Cheers,
Rob
