personally i would vote for having them defined as EXPORT_OK symbols in the
perl modules, that way they don't really cost anything or clog up the name
space unless you ask for them. you can either import the constants use Gtk2
qw/PANGO_WEIGHT_BOLD etc/ or refer just to them as Gtk2::Pango->WEIGHT_BOLD.
at least something of that nature. i don't really think apps should have to
know what the values are, beyond that it's dangerous if the value were to
change. the perl module could even have code to get them from the c libraries
at compile if it was deemed nec.
