When I tried to install RcppArmadillo, I got the following error message:

* installing *source* package 'RcppArmadillo' ...
** package 'RcppArmadillo' successfully unpacked and MD5 sums checked
./configure: not found
ERROR: configuration failed for package 'RcppArmadillo'
* removing '/usr/local/lib/R/library/RcppArmadillo'

I don't know how to solve this problem.

Any help will be appreciated.
