Hi!

Meld uses gtk and gtksourceview from python via gobject interface.
For this to work several things a required. Unfortunately I can't name exact 
packages for RHEL, so here is an approximated list
1) python-gobject support. You already have this, since you have 
"/python/v2.7.10/lib/python2.7/site-packages/gi/__init__.py" file
2) Gtk+3 & gtksource libraries >= 3.14. To verify their presence ensure that 
you can run gedit and check its version is >= 3.14
3) gobject introspection repository ("gir" or "typelib") for Gtk+3 & gtksource. 
It seems that you lack this.
It it is stored in files like "Gtk-3.0.typelib" and "GtkSource-3.0.typelib" in 
folder like girepository-1.0/ somewhere in the /usr
If you doesn't have these files anywhere in the /usr it looks like installing 
some package containing them would help.
