Well I would if I had it sitting around =). I did try to compile
one... but chickened out as soon as I hit an error:
$ make
`sh cflags perly.o` perly.c
CCCMD = cc -c -O

How about something like the below? Basically If we find "This is
perl v4" we bail right then. Otherwise we use the version check I
proposed up-thread? I may have inadvertently used some
bash/gnu-isms... sorry about that.
