get pkg_add to use real package names

[fbsd_user]

I have been trying to get the pkg_add -r  command to
work using the real full package names.
IE: qpopper-4.0.5_1.tgz

pkg_add -r  defaults to going to
pub/FreeBSD/ports/i386/packages-4.8-release/Latest/
and the name there is qpopper.

Problem is I can not find any way to find this name
spelled like that. FBSD handbook says to use
http://www.freebsd.org/ports/index.html or
http://www.freebsd.org/ports/master-index.html to
locate the package name, those web pages gives the
name as qpopper-4.0.5_1

So I am trying to change pkg_add environment variable
to point to different directory location as shown below.
Every thing looks fine, except pkg_add says it can not find it.

Please review what I have posted below to see if I am missing
something simple.

Thanks
Joe

Using the following script, I can verify access
to the FBSD ftp sites and download package using
official name qpopper-4.0.5_1.tgz


This is my working script

#! /bin/sh
cd /usr/packages/
path=pub/FreeBSD/ports/i386/packages-4.8-release/mail
ftp -av ftp://ftp2.freebsd.org/$path/qpopper-4.0.5_1.tgz

Here is the output display messages from this script

So I have proof it lives where I think it does and can find it and
download it.


# /root >setenv PACKAGESITE
"ftp://ftp2.freebsd.org/pub/FreeBSD/ports/i386/packages-4.8-release"

Setenv is the same path as in my script.
PACKAGESITE is the environment variable for pkg__add  command.

# /root >pkg__add  /mail/qpopper-4.0.5_1
test without .tgz  and it get's appended by pkg_add

We know the error 'file not found' is incorrect
because we just FTP to it direct, so it must be
the ' no access' error, which makes no scenes.

I know that 5.2 is being readied for release.
Is pkg_add written in some way that the ftp server
can ignore it's request for service
and native ftp still gets serviced?

Any in-sight into how FBSD ftp servers work or
help on the setting the PACKAGESITE environment variable
would be greatly appreciated.

Thanks
