Some packdges like (Zope and Mysql), have trouble to untar with Sun tar, the solution is download and install Gnu tar, you can download Gnu tar in pkgadd format from:

http://sunfreeware.com

however your problem seems to be that is a tar within a Gzip so you need first to ungzip:

# gzip -d psyBNC2.2.1BETA.tar.gz
this shoul return psyBNC2.2.1BETA.tar, then untar:
# tar xvf psyBNC2.2.1BETA.tar

just an added comment....
if you do not have the gzip utility on your machine,
you can get it at

http://www.sunfreeware.com

for either a
sparc or intel processor.

Quicker method....

# gunzip -c psyBNC2.2.1BETA.tar.gz | tar xvf -

You still need to install gzip utilities, but this way is one command and doesn't uncompress the file onto your drive, it just redirects the uncompressed output to tar.

even quicker yet, gnu tar can gunzip and untar with one command.
