Installing p5-perl-ldap

[opalit]

I have installed postfix forwarder and in order to read Active directory the following command has to be run /usr/sbin/pkg_add -r p5-perl-ldap

All I get is write failed line after line after line, I have re-mounted the compact flash RW but it makes no difference

I am a newby to command line FreeBSD, Unix or Linux, I am a Windows Man really, how do I install this required package.
