2: In install.packages(...) :
  installation of package ‘org.Hs.eg.db’ had non-zero exit status

This seems to be due to a corrupted download.

Notice:

Error in untar2(tarfile, files, list, exdir, restore_times) :

and also note that there is a length problem.:

1: In download.file(url, destfile, method, mode = "wb", ...) :
  downloaded length 8908800 != reported length 79959831

So please try again. Confirm, though, that you have sufficient HDD space (also at the temp location).
