 If a port has an underscore ('_') in its version, then any attempt to
 install it will result in a registry error:

 {{{
 Error: Target org.macports.activate returned: Registry error: No port of
 <port> installed.
 }}}

 Examples include aspell-dict-it, whose version is 2.2_20050523-0, and
 aspell-dict-pl, whose version is 6.0_20061121-0.

 I have worked around this problem by editing the Portfile to a) manually
 substitute the original value of version into the distname, and b)
 changing the underscore in the version to a dash ('-').

 I suspect that something in the registry lookup is scanning for the
 "_${revision}" that's appended to the port version, but it is scanning
 forward for the underscore starting at the beginning of the string instead
 of scanning backward from the end.
