Could you show me how you formatted the nt database?

This is usually an issue when either the BLASTDB entry in .ncbirc is
incorrect, or you are missing the nt database (really, that the nt
database has not been formatted)

Ok, this is a formatting issue. Could you show me all the steps that you
used to format the database, including which directory you put them in?

Umm... this is not a good idea. You likely want blastall in /usr/bin,
and you want it with 755 permissions
cp /root/bin/blastall /usr/bin
chmod 755 /usr/bin/blastall # makes blastall rwxr-xr-x

If you use our rpms from
http://downloads.scalableinformatics.com/downloads/ncbi/ you should have
it installed in the right location (along with the scoring matrices).
Then you need to construct your .ncbirc to look like
[NCBI]
Data=/usr/share/ncbi/data
[BLAST]
BLASTDB=/data/
make sure /data is world readable/writeable
chmod 777 /data
and place your nt in /data , and format it
cd /data
formatdb -o T -v 1024 -p F nt
(use anything from 256 to 8192 as the argument to -v, it depends upon
the amount of memory in your machine)
