I doubt that it will help, but if you want to try 0.48, skip the following step of the OP:

perl -i.bak -pe"s/config => \{ cc => \$cc, ld => \K(?=\$cc })/\$cc eq 
+'cl' ? 'link' : /" lib\Alien\wxWidgets\Utility.pm
[download]

The only difference between 0.47 and 0.48 is a fix that addresses the same problem as the patch applied by that step.
