Comment(by raimue@…):

 {{{
 livecheck.regex ${name}-(\[0-9.\]+)
 }}}

 I would say this sdlconsole regex is wrong, as this also matches the dot
 of `.tar.gz` in the string `sdlconsole-2.1.tar.gz` and thus, the result of
 the match is `2.1.`

 There are multiple options to fix the regex which are compatible to
 previous releases of MacPorts:
 {{{
 livecheck.regex ${name}-(\[0-9.\]+)\.tar
 livecheck.regex ${name}-(\\d+(?:\\.\\d+)+)
 }}}
