I appreciate your R7RS debugging effort.  Thanks!

I believe you’re mistaken.  At least, the manual says:

 -- syntax: export variable ...
     Add all VARIABLEs (which must be symbols or pairs of symbols) to
     the list of exported bindings of the current module.  If VARIABLE
     is a pair, its ‘car’ gives the name of the variable as seen by the
     current module and its ‘cdr’ specifies a name for the binding in
     the current module’s public interface.

Using pairs in Guile’s ‘export’ (or ‘#:export’ in ‘define-module’)
should be the same as ‘rename’ from R7RS.

HTH!
