Package name is not consistent ???-what does it mean?

[Siju George <sgeorge_(_dot_)_ml_(_at_)_gmail_(_dot_)_com>]

Hi all,

I have the package 

squid_2.5.STABLE6.tgz

copied to my 

/tmp

directory.

>From the same directory I gave the command

#pkg_add squid_2.5.STABLE6.tgz

then I get the message

#Adding squid_2.5.STABLE6.tgz
#Package name is not consistent ???

and the package is not added!

Could someone point out the problem :)

I used to add packages via ftp and it worked fine till now!

Now the net connections are a bit slow and unsteady :)

Thankyou

KInd Regards

Siju
