>Description:
rrdtool was built from ports tree with following make.conf options recommended to disable man files creation:

freebsd81# cat /etc/make.conf
NOMANPAGES=1
NOPORTDOCS=1
NODOCS=1
MANPREFIX=/tmp/

freebsd81# pkg_info -v -x rrdtool | grep File | head
File: lib/python2.6/site-packages/py_rrdtool-0.2.1-py2.6.egg-info
File: /tmp//man/man1/bin_dec_hex.1.gz
File: /tmp//man/man1/cdeftutorial.1.gz

next, pkg_info -g 
freebsd81# pkg_info -g -x rrdtool
Information for rrdtool-1.4.5:

Mismatched Checksums:
pkg_info: /usr/local//tmp//man/man1/bin_dec_hex.1.gz doesn't exist
pkg_info: /usr/local//tmp//man/man1/cdeftutorial.1.gz doesn't exist
pkg_info: /usr/local//tmp//man/man1/rpntutorial.1.gz doesn't exist
pkg_info: /usr/local//tmp//man/man1/rrd-beginners.1.gz doesn't exist

as you can see, pkg_info -v shows correct paths of 'installed' man files (e.g. /tmp/), but pkg_info -g thinks that local user prefix (/usr/local/) should be added (note the double slash) to them as well, which is wrong. 

I guess proper digging through sources could help find similar issues more critical than this one.
>How-To-Repeat:
