But actually no, wait, it will not work in sbopkg with the default
settings:

     Processing dstat

     dstat:
     Found v0.7.4.tar.gz in /var/cache/sbopkg.
     Checking MD5SUM:
       MD5SUM check for v0.7.4.tar.gz ... OK
     Building package for dstat...
     tar: /var/lib/sbopkg/local/system/dstat/dstat-0.7.4.tar.gz: Cannot 
open: No such file or directory
     tar: Error is not recoverable: exiting now
     tar: /var/lib/sbopkg/local/system/dstat/0.7.4.tar.gz: Cannot open: 
No such file or directory
     tar: Error is not recoverable: exiting now

     dstat:
     Would you like to continue processing the rest of the
     queue or would you like to abort?  If this failed
     package is a dependency of another package in the queue
     then it may not make sense to continue.

     (Y)es to continue, (N)o to abort, (R)etry the build?:

Some slackbuilds try multiple tarball names and dstat does it too but
it uses incorrect name, it should be:

     tar xvf $CWD/$PRGNAM-$VERSION.tar.gz || tar xvf 
$CWD/v$VERSION.tar.gz

There is a similar problem in network/ngrep but this script is more
optimistic and does not try different tarballs:

     tar xvf $CWD/$PRGNAM-$SOURCEVERSION.tar.gz

It will not work with sbopkg neither.

And there is network/radicale/radicale.SlackBuild which tries 3
different tarball names including the version with `v` at the
beginning that dstat has missed but it isn't checked in $CWD:

     tar xvf $CWD/$PRGNAM-$VERSION.tar.gz || tar xvf 
$CWD/Radicale-$VERSION.tar.gz || tar xvf v$VERSION.tar.gz

so that will not work neither. Interestingly in this case wget gets a
correct filename even w/o using --content-disposition:

     $ wget
