MacPorts 2.7.0-beta2 now available for testing

[Joshua Root]

Source code and pkgs for MacPorts 2.7.0-beta2 are now
available [1]. Testing of either of these install methods is helpful.

Be prepared to encounter bugs. As always, having a recent backup would
be wise. Please report any bugs that you find [2] (after first searching
Trac [3], of course!)

There are a large number of changes in this release. See the ChangeLog
[4] for a list of most of the major ones. You may like to focus your
testing on the new features in that list, as well as your normal usage.

Notable changes since beta1 are:
  * Fixed an error that could occur when applying the previously
    requested variants when upgrading. (Ticket #62751)
  * Fixed progress bar width when COLUMNS is not set in the environment.
  * Fixed inability to read the registry database without write
    permission when using newer SQLite versions.

Known issue: This change needs to be applied on 10.6 and older to 
successfully build base against the system SQLite:
