gtk2/pango apps taking *forever* to startup

[Jeremy Huddleston]

Is anyone else seeing performance issues with gtk2 based  
applications?  I'm on SnowLeopard with mostly updated versions of  
ports (where they actually build).

xchat takes about 10 minutes to display the connections window (gtk- 
demo has the same issue).  Here's a 30-second sample about 4 minutes  
into the launch (gtk-demo's sample looks the same):

It's fairly deep, and here are the big tickets:

Sort by top of stack, same collapsed (when >= 5):
         hb_ot_layout_substitute_lookup        6768
         hb_ot_layout_position_lookup        6704
         PosLookupSubTable::apply(_hb_ot_layout_context_t*,  
_hb_buffer_t*, unsigned int, unsigned int, unsigned int, unsigned int,  
unsigned int) const        5438
         SubstLookupSubTable::apply(_hb_ot_layout_context_t*,  
_hb_buffer_t*, unsigned int, unsigned int, unsigned int, unsigned int,  
unsigned int) const        5191

Is anyone else experiencing this problem?
