A similar error report drive me crazy (its not a long drive) for a 
couple of months, until I stumbled onto something that finally gave 
me a meaningfull error message.

See if you have an /etc/pango/pango.modules file.  In my case it was 
totally missing.  The file is a self-scan result, and can be 
regenerated if its fubared by rerunning /usr/bin/pango-querymodules32
and redirecting it output to that file.

#>cd /etc/pango
#>/usr/bin/pango-querymodules32 >pango.modules

If the error persists, then something in the pango install may be 
fubar.  But I had forceably reinstalled anything libxml2 or pango 
related 6 or more times without resolving this on my system.

IMNSHO, the pango post install script is busted for not doing that 
little bit of housekeeping regardless of whether or not its needed.  
Its a bit like re-running ldconfig when a new library has been 
installed, it can't hurt, and it would have helped immensely.
