I don't know what you mean by "eval no longer works", I guess.  See what
Paul said.

CGI.pm is better in general.  I don't know what isn't working for you, so I
cannot say offhand if it would work or not.

For flock, you are stuck.  There's no easy way around it.  For file paths,
use File::Spec, File::Basename, etc.  For \r\n ... don't use them together
at all, ever, for portable programs.  Use \015\012 for socket
communications, and \n for local newline.

perlport has all this information and more.  Anyone who is doing
cross-platform programming in Perl should read it.
