This is the main problem - it is saying there is no default assignment
operator (because one of the members in pair is const). The solution is
to avoid assignment. I've attached a patch to do this plus some error
message corrections.

All of guile's interface files now use the scm interface.
This should not affect any users. Swig generated code
using the scm interface can be mixed with gh interface
using user code.
It does simplify maintenance of the guile swig code though.
