It seems it want a numeric value, but is there a numeric value for LOG_PID?
man 3 syslog

It's a constant in syslog.h

Get rid of use constant. And get rid of @{[ LOGPID ]} - what is that for anyway? Constants should be bitwise or-ed. Like this: LOG_PID | LOG_CONS | LOG_WHATEVER. Those should be constants exported by Unix::Syslog, not your own.
