Vmware tools install instructions won't work for pfsense version 2.1.4

[snm777]

Please forgive me if this turns out to be a simple fix, but I'm a freebsd noob, and this problem has me at a standstill.

I am attempting to install the VMware supplied VMware tools on a pfsense vm so I can use the VMXNET 3 adaptor type - I have need for high throughput, not VLAN tagging or any other things "lost" by not using the E1000 type.  I tried using the OPen tools, but I can't see VMXNET 3 interfaces with the Open tools installed.
To that end, I found this guide:
https://doc.pfsense.org/index.php/VMware_Tools
When I attempt to install ANY package using pkg_add, I get an error.  For instance:
pkg_add -rv perl
returns
Error:  Unable to get ftp://ftp.freebsd.org/pub/FreeBSD/ports/amd64/packages-8.3-release/Latest/perl.tbz:  File unavilable (e.g., file not found, no access)

That error is spot on - if you visit ftp://ftp.freebsd.org/pub/FreeBSD/ports/amd64/ you will see that there is no packages-8.3-release folder - jsut packages-8.4-release.

How can I overcome this?  I am assuming I can't change the underlying freebsd to 8.4 without potentially breaking pfsense, is there someplace (another repository, perhaps?) that the 8.3 release files still exist?  If so, how do I get to them?  Any help or pointers would be appreciated, thanks!

FreeBSD 8.3 has been archived and moved to a different FTP server.  Try

pkg_add -rvf ftp://ftp-archive.freebsd.org/pub/FreeBSD-Archive/ports/amd64/packages-8.3-release/Latest/perl.tbz

Thank you very much.  Just after I posted this, I found instructions telling me to run
setenv PACKAGESITE ftp://ftp-archive.freebsd.org/pub/FreeBSD-Archive/ports/amd64/packages-8.3-release/Latest/

at which point I followed the instructions on the original instructions and everything installed.  Thank you very much for the answer!

/random when i rebooted, I'd told vmware to conenct my VMXNET3 adaptors, and to NOT connect my E1000 adaptors - instead it connected the E1000, so I shut down, removed the E1000's, and booted back up with JUST the vmxnet3's connected and it worked.  in case anyone else tries to do what I did and hedge their bets by having both adaptor types installed at the same time :)
