| Thanks Dirk.  Unfortunately, I have loaded the latest QuantLib (1.18 I think) - still same RQuantLib install error.  I loaded the items you indicate, still same RQuantLib install error. Could there a library still "lingering" somewhere in my system from a previous "bad" install?  How might I completely purge QuantLib so that I can restart from the tar file downloaded from quantlib.org?

We would need more details. I am on 19.10, everything works and should / will
once upgraded. I would recommend you check and double-check all components: R
(works, I presume), Rcpp, QuantLib and then RQuantLib.

edd@rob:~$ lsb_release -a

ii quantlib-examples 1.18-1.1910.1

edd@rob:~$ Rscript -e 'library(RQuantLib); packageVersion("RQuantLib")'

So my RQuantLib is from source.
