It sounds like you are using a Perl which was built with thread support. You can find this out with:

perl -V | grep archname=

or:

perl -V | grep useithreads=

In the first example, the archname usually indicates if it is a threaded Perl. On my threaded version of 5.10.0, I get:

osname=linux, osvers=3.13.0-24-generic, archname=x86_64-linux-thread-multi

In the second example, you are looking to see if useithreads is set to define. Again, from my threaded 5.10.0 install:

useithreads=define, usemultiplicity=define

Try installing a non-threaded Perl and set Apache to use that instead of the system Perl. How to do that is left as an exercise for the reader, as it is beyond the scope of the question. However, something like Plenv or Perlbrew can make that relatively painless.
