IMO rebuilding is the easy and straightforward way... seems
you want it the hard way.

PANGO_RC_FILE points to `pangorc' file, not to pango.modules.
Most likely you don't have any pangorc as most people don't
need it.  However, you are in a situation you might use one.
Put something like

  ModuleFiles = /opt/gtk2/etc/pango/pango.modules

  AliasFiles = /opt/gtk2/etc/pango/pangox.aliases

there, point PANGO_RC_FILE to it and run

  pango-querymodules >/opt/gtk2/etc/pango/pango.modules

Anything Pango should find pangorc and consequently
pango.modules and consequently the modules now -- provided
that it has PANGO_RC_FILE properly set.

And only fixing Gtk+ input methods, pixbuf loaders, default
rc, theme engines, ... remains.
