Simon, Carlos, Prateek,
It's an issue between R and guitar. Rcpp is an bystander.
Upon cloning and running R CMD INSTALL we see it end on
*** installing help indices
** building package indices
** testing if installed package can be loaded

We had the same thing in the Rcpp examples and did this:
2015-08-26 Dirk Eddelbuettel <e...@debian.org>
* inst/unitTests/testRcppClass/src/rcpp_module.cpp: Renamed Module
'World' to 'RcppClassWorld' to avoid multiple modules with same name
(pull request #351, fixed issue #350)
* inst/unitTests/testRcppClass/man/Rcpp_class_examples.Rd: Ditto
* inst/unitTests/testRcppClass/R/load.R: Ditto
* inst/unitTests/testRcppClass/NAMESPACE: Ditto
* inst/unitTests/runit.Module.client.package.R: Re-enable test
* inst/unitTests/testRcppModule/src/rcpp_module.cpp: Renamed Module
'World' to 'RcppModuleWorld' to avoid multiple modules with same name
* inst/unitTests/cpp/modref.cpp: Rename 'World' to 'ModRefWorld'
* inst/unitTests/runit.modref.R (test.modRef): Ditto
* inst/unitTests/cpp/Module.cpp: Rename 'World' to 'ModuleWorld'
* inst/unitTests/runit.Module.R (test.Module): Ditto
2015-08-25 Kurt Hornik <kurt.hor...@wu.ac.at>
* R/loadModule.R: For now=TRUE, always set .botched to FALSE which
corresponds to the case of the methods package being in the search path
* inst/include/Rcpp/Reference.h: Call call with the internal Namespace
Something was changed (by MMae as I recall) in that period that affects the
name lookup and you simply cannot more than one reference to the same name.
I have not yet looked into guitar -- it may just be that its build is weird
and symbols appear multiple times.
But "someone" needs to disentangle this.
Dirk
