Cannot build a complete environment with jhbuildrc

Hi guys,

Since some days ago, I cannot build through "jhbuildrc" the complete
Gtkmm environment that I need to work...

The problem seems that the mm wrappers request a newer versions of g
libraries. For example,

---
Configure: error: Package requirements (sigc++-2.0 >= 2.0.10 glib-2.0
>= 2.31.0 gobject-2.0 >= 2.31.0 gmodule-2.0 >= 2.31.0) were not met:

Requested 'glib-2.0 >= 2.31.0' but version of GLib is 2.30.2
Requested 'gobject-2.0 >= 2.31.0' but version of GObject is 2.30.2
Requested 'gmodule-2.0 >= 2.31.0' but version of GModule is 2.30.2

*** Error during phase configure of glibmm: ##########

I don't know who maintain this system/repository, so but... what could I do ?
