problems with psnfss and (separately) bind

[travis breaux <st3ck@bayou.uh.edu>]

	The problems I have are with psnfss-5.2-1.deb and the
bind-4.9.3-P1-2.deb during the dselect installation. psnfss-5.2-1.deb
throws out at me the following lines during unpacking:

Unpacking psnfss (from .../debian/stable/binary/tex/psnfss-5.2-1.deb) ...
dpkg - warning, overriding problem because you used --force:
 trying to overwrite `/usr/lib/texmf/tex/latex/psnfss/OMLhlh.fd', which is

dpkg - warning, overriding problem because you used --force:

dpkg: error processing /root/debian/stable/binary/tex/psnfss-5.2-1.deb
(--insta:
 corrupted filesystem tarfile - corrupted package archive

	I ftp'd it from two mirrors and debian.org as well, still ended
with the same problem. Since all I used was dselect on the package I can
only assume it would be a structural error with the package itself. With
the bind package:

/var/lib/dpkg/info/bind.postinst: _: command not found
dpkg: error processing bind (--install):
 subprocess post-installation script returned error exit status 1

I would think this would also to be a distribution error. I surely haven't
had much experience with the details of dpkg or dselect, inevitably that's
where I am headed. But until I become the true debian package mastermind,
has anyone successfully installed (or come into error with) 
psnfss-5.2-1.deb? And, are the scripts in /var/lib/dpkg/info from the
packages themselves (I could only imagine they would be) or do they live
somewhere else?

thanks,
travis
