This support site is intended to help people with questions about Bioconductor packages. The partialAR package isn't even an CRAN package any longer, having been demoted due to not passing R CMD check. Which means it wasn't compiling at that time, and there are no updates to indicate that the problem has been fixed.

Anyway, your best recourse is to contact the maintainer directly and see if you can get help there.
