Hi Dan,

   Thanks for using the PRF.

There are some glitches with ./configure, I recommend you avoid using
./configure and instead use the "classic" method of
configuring/compiling ACE.  Please see

ACE_ROOT/ACE-INSTALL.html#unix_traditional

Naturally, if you or someone else would like to fix the problems with
./configure that would be great!

Thanks,

        Doug
