even after performing a "make all" there was no such file... all of the prerequisites were up to date.

as far as IO::Socket, I have it as part of the base perl install... if it were my decision, I'd test 5.6.1 against our existing code, but alas, it is not my decision to make... and since any changes to the existing system must be done within the packaging system, I can't do CPAN updates. :\
