>Description:
The code in "pkg_add" which checks for conflicts during installation creates
too generic patterns:

        if ((s=strrchr(PkgName, '-')) != NULL){
            strcpy(buf, PkgName);
            buf[s-PkgName+1]='*';
            buf[s-PkgName+2]='\0';

So "foobar-x.y" gets turned into "foobar-*" which will match sub packages
like "foobar-sub-x.y", too.

>How-To-Repeat:
Try to add e.g. the "teTeX" meta package:

tron@lyssa:/usr/pkgsrc/print/teTeX#pkg_add /src/packages/All/teTeX-1.0.6.tgz
pkg_add: other version 'teTeX-sharesrc-1.0' already installed
