Run this command on your machine and post the output: perl -V

      For your 5.10 version this: archname=i686-linux-thread-multi and these: useithreads=define, usemultiplicity=define & this  USE_ITHREADS are all telling you it is compiled for multi-threading.

      Conversely, your 5.8.8 has this: archname=i686-linux and these:usethreads=undef use5005threads=undef useithreads=undef usemultiplicity=undef telling you it is not.
