Compilation errors in cgi-bin/ljprotocol.pl?

When I do a perl -c cgi-bin/ljprotocol.pl on a cleanly checked-out version directly from CVS, I get compilation errors:

Bareword "LJ::BMAX_SUBJECT" not allowed while "strict subs" in use at cgi-bin/ljprotocol.pl line 405.
Bareword "LJ::CMAX_SUBJECT" not allowed while "strict subs" in use at cgi-bin/ljprotocol.pl line 405.
Bareword "LJ::BMAX_EVENT" not allowed while "strict subs" in use at cgi-bin/ljprotocol.pl line 406.
Bareword "LJ::CMAX_EVENT" not allowed while "strict subs" in use at cgi-bin/ljprotocol.pl line 406.
Bareword "LJ::BMAX_PROP" not allowed while "strict subs" in use at cgi-bin/ljprotocol.pl line 408.
Bareword "LJ::CMAX_PROP" not allowed while "strict subs" in use at cgi-bin/ljprotocol.pl line 408.
cgi-bin/ljprotocol.pl had compilation errors.

Any ideas?
