Can you please send us the commands that you have executed?
If you used "pkg_add -r <package name>" then the name of the package can 
be a general package name, without version number. This is useful since 
usually you are not sure what is the latest version, you just want to 
install it. Here is an example:

messias# pkg_add -r mc
Fetching 
ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-6.1-release/Latest/mc.tbz... 
Done.
pkg_add: package 'mc-4.6.1_3' or its older version already installed

However, if you add a package that is saved locally, you need to type in 
its full name (or path):

pkg_add mc-4.6.1_3.tbz

or something similar. Once you have the package/port installed, you can 
lookup its full name with pkg_which:

messias# pkg_which mc
mc-4.6.1_4

When you need to delete a package, you need to specify the full name 
(including the version number). The reason for this is easy: it is 
possible to have different versions of the same package installed at the 
same time. (Well, this is not true for some packages, but it is true for 
others...)

So instead of doing:

pkg_delete mc

you should use:

pkg_delete mc-4.6.1_4

I hope this answers your question. If it does, then probably reading 
these man pages will help you a LOT:

portupgrade(1)
pkg_add(1)
pkg_deinstall(1)
pkg_delete(1)
pkg_glob(1)
pkg_info(1)
pkg_sort(1)
pkg_update(1)
pkgdb(1)
ports_glob(1)
portsclean(1)
portsdb(1)
portversion(1)
pkgtools.conf(5)
ports(7)


Best,
