I keep getting this message:

Error including libraries:
syntax error at links.cfg line 154, near
"my %months = map { $_ => $i++ } qw!Jan Feb Mar Apr May Jun Jul
Aug Sep Oct Nov Dec"
(Might be a runaway multi-line DD string starting on line 136)
syntax error at links.cfg line 173, near "my @months = qw!Jan Feb "
(Might be a runaway multi-line !! string starting on line 150)
syntax error at links.cfg line 179, near "}"

I have double checked permissions and links.cfg setup. What am I doing wrong?
