reclaim does not support distfile tags

[ryandesign (Ryan Carsten Schmidt)]

port reclaim does not support tags -- the labels that can be added after a colon to distfiles and master_sites values to group them.

A port might specify its distfiles as:

distfiles           foo.tar.gz:foosite \
                    bar.tar.gz:barsite

This means "download the file 'foo.tar.gz' from the site with the tag 'foosite' and the file 'bar.tar.gz' from the site with the tag 'barsite'". Such a port would then specify its master_sites as:

master_sites        https://foo.example.com/fooproject/:foosite \
                    https://bar.example.com/barproject/:barsite

This would cause MacPorts to download the files https://foo.example.com/fooproject/foo.tar.gz and https://bar.example.com/barproject/bar.tar.gz.

port reclaim is not aware of this feature; it just uses each element of distfiles literally. So it checks the disk for the files "foo.tar.gz:foosite" and "bar.tar.gz:barsite", which of course don't exist.

Implementing support for tags requires using the procedures getdistsite and getdisttag from portutil.tcl​. Take a look at the other places in base that use these procedures.
