[R] error in R CMD build when editing c function in R package

[moli]

I have modified a C function in the `phmm` package. Now I want to rebuild the
package, but the following error occurred. How can I fix the error?
  

    $ cd ~/Desktop/phmmw
    $ R CMD build phmm
    * checking for file ‘phmm/DESCRIPTION’ ... OK
    * preparing ‘phmm’:
    * checking DESCRIPTION meta-information ... OK
    * cleaning src
    * installing the package to re-build vignettes
          -----------------------------------
    * installing *source* package ‘phmm’ ...
