Log Message:
* Create APACHE_MPM variable that can be either "prefork" or \ 
"worker"
  (defaulting to "prefork") that chooses the multi-processing model
  for apache to handle requests.  "Prefork" is the method used by
  Apache-1.3, which is non-threaded.  "Worker" uses threads to handle
  requests.

* Fix libtool usage in this package.  Apache uses libtool, but is
  hardcoded to use the libtool installed by devel/apr.  Patch the
  generated makefile fragment to use a local libtool instead, and
  allow the usual libtool wrapper to take its place.
