Thanks for working on Solaris.  

You may well be the only non-member of R Core who does so --- Prof Ripley
usually complains to us when Rcpp breaks there, and we usually just shrug our
shoulders and point out that our hands are tied: no Solaris machine either
one of us can access, so no (meaningful) way to work on fixes.

But more recently, Martyn Plummer (CC'ed) provided two excellent patches
which helped a lot.  With those, we now have Rcpp 0.9.7, and Solaris builds
on Prof Ripley's test systems, or at least the x86-based one.  Sparc still
fails as per the results page linked from CRAN's results page for Rcpp.

Now, for the backtrace and backtrace_symbols symbols were not declared.
Grep'ing for this I found

edd at max:~$ grep -rin backtrace svn/rcpp/pkg/Rcpp/src/*
svn/rcpp/pkg/Rcpp/src/debugging.cpp:56:    stack_depth = backtrace(stack_addrs, max_depth);
svn/rcpp/pkg/Rcpp/src/debugging.cpp:57:    stack_strings = backtrace_symbols(stack_addrs, stack_depth);
svn/rcpp/pkg/Rcpp/src/debugging.cpp:67:    free(stack_strings); // malloc()ed by backtrace_symbols
edd at max:~$ 

and indeed, in debugging.cpp I see

#else // ! (defined(WIN32) || defined(__FreeBSD__) || defined(__NetBSD__) || defined(__OpenBSD__) 

which is lacking a Solaris test -- I may need to add    || defined(__SUNPRO_CC)   
test as well.

Could you try locally if that works?  Maybe Google can suggest another
Solaris variable to test for too?
